How to make pool water clear and blue with and without chemicals. The water in the pool turns green: why and what to do. Why is the pool water green? What to do if the pool turns green?

People who have a swimming pool may experience blooms in the pool water. This happens to everyone, the only question is time. There are many special products that are designed specifically for water disinfection, but, no matter what, dealing with the problem of green water and its unpleasant odor very difficult.

The reasons why the process of blooming of basin water occurs

The pool is a very good breeding ground for various microorganisms. There are many factors that contribute to this:

• Presence of organic matter. If the pool is located outside, leaves and other debris may fall into it. All this is excellent food for microorganisms.
• Warm. Bathing requires warm water, and it is excellent for the growth of algae and bacteria.
• Light. Algae need it.

Ways to eliminate green water in the pool

If the water in the pool turns green, then what should you do? It is necessary to understand that the products that can be purchased on the market are effective, but only for a while. But, nevertheless, when water blooms, it is necessary to take other measures in addition to chemicals. There can be many reasons for flowering, so the approach to this problem should be comprehensive.

But still, why does the water in the pool turn green? The main reason for this phenomenon is that brown and green algae bloom. Their spores move through the air into the water, and their active growth occurs.

To eliminate this problem, you can treat the liquid with chlorine. You can also use special preparations called algaecides instead. They, unlike chlorine, cannot cause allergic reactions, but, accordingly, their cost is higher. If the water turns green due to lack of circulation, then this cause can be eliminated and the water will become normal again. If you use chlorine, then you need to know that its standards should not go beyond sanitary and epidemiological limits, that is, not exceed 3 mg per liter.

There are other methods of water disinfection - the use of ultraviolet light and ozonation. These options are very highly effective, but they are not used often.

Ozonizers have a very high cost, so few people can afford to buy them, and ultraviolet lamps are not profitable to use from an economic point of view, especially if the pool is large.

Stages of the blooming water purification mechanism:

• Preliminary protection is needed;
• Blooming water must be filtered;
• The use of special means that prevent the proliferation of harmful microorganisms.

Let's try to understand each stage in more detail.

Preliminary protection

If you use water to fill your pool that already contains microorganisms (that is, water from a reservoir or rainwater), then you need to put in a lot more effort to clean it. It is very good if there is an awning or a protective cover. After all, these things can prevent access sunlight and garbage. If such a cover is not available, then you need to try to do everything possible to purchase it. A cover or awning is not expensive.

Water filtration

You need to know the fact that throughout the day an amount of water corresponding to two to three volumes of the pool should pass through the filter. If it spends more, then this is a definite plus. Basically, all pools are equipped with a filter and pump. They can be combined in one building, but this is already in inexpensive models. If the filter operates with sufficient power, the water bloom will not be so intense. You can calculate how long a day the pump should run. For convenience, you can use automatic timers.

The use of agents that prevent the proliferation of microorganisms

When there is algal bloom in the pool, be sure to use an anti-algal bloom remedy. Most best option– contact special services involved in pool maintenance and water treatment. After taking a water sample and analyzing it, they will be able to choose the most effective remedy to fix the problem. If measures are not taken in a timely manner, it will be necessary to drain the pool and rinse it with water saturated with special chemicals. If there is algae, then you need to carry out mechanical cleaning. Only after such measures can water be released into the pool again.

How to get rid of green pool water and why it turns green. - Blog about swimming pools

Why did the water in the pool turn green?

Depending on weather conditions, this can happen quickly - almost instantly. Your water looks fine one day, and the next it turns green, green, not water, but a swamp. The green color you see is a full-blown algae bloom.

Algae are microscopic plants that fall into pools with rain or are carried through the air, such as dust. Some are free-floating, while others are attached and cling to the walls of the pool. In any case, you will be able to clean your pool, so do not despair - within one or two days your water will be crystal clear.

Instructions for combating algae in the pool.

You will need it.

2 Use your test kit to determine the pH level of your pool water. It should be between 7.2 and 7.6. If it is outside this range add pH plus or pH minus to adjust the level.

3 Use a brush on the sides and bottom of the pool to loosen the algae's grip on the pool surface.

4 Add unstabilized chlorine granules (powder) to the pool. The amount of chlorine you add will depend on the volume of your pool (150 grams for every 10,000 gallons or about 5 ounces of chlorine for every 2,500 gallons of water).

5 Turn on the pump and run the filtration system, throughout the day the chlorinated water circulates and rids the water of algae.

6 Collect white sediment from the bottom of the pool using a water vacuum cleaner the next day. The water will have to be substantially purified if it still has green repeat the “shock” process.

7 Backwash the filter.

8 Add the required amount of water to the pool, the amount of which will decrease during this treatment.

Tips and warnings

Clean your pool regularly with a wet vacuum, and keep your pool water balanced (PH should be between 7.2 and 7.6 and free chlorine levels should be between 1.0 and 3.0 ppm).

During periods of hot weather or when you have high water load (large numbers of swimmers), shock your pool every two weeks to prevent algae from taking over your pool.

Use an algaecide that prevents algae from forming in pool water.

After the “shocking” water treatment, you should not swim in the pool for at least one day. High level Chlorine may cause eye or skin irritation and damage to swimwear.

The water in the pool is turning green, what to do /

A swimming pool, especially one located outside, brings special pleasure to its owners, especially during periods of elevated temperatures. The water in it provides an excellent opportunity to refresh yourself without leaving your home. But, like everything that surrounds us, the pool, and especially the water, requires special care and maintenance. The garbage that the wind brings and we leave behind, various types of pollution, bacteria, as well as the process of water blooming - these are the problems that should be dealt with.

Why does the water turn green?

If debris and dirt can be easily dealt with by cleaning the pool or changing the water, then green liquid is a real problem. Why does it occur?

Flowering of the water surface occurs especially actively in the warm season. This process is caused by the proliferation of special microorganisms, namely green and brown algae. They are not like the algae we are used to. These are microscopic organisms that reproduce at an incredible rate and densely cover the bottom and walls of the pool. The reproduction process occurs in an ideal environment for them:

• Humidity;
• Sufficient sunlight;
• Warm;
• “Food” - leaves, debris and anything that can get into the pool serves as a good treat for these microorganisms.

Such an environment is more than conducive to water blooming, and this process is just a matter of time if appropriate measures are not taken.

Ways to fight

In order to prevent the flowering process, it is necessary to ensure that the liquid in the pool is always as clean as possible. To do this, you need to install a filter in the pool. It will help maintain the required level of cleanliness in the pool. In addition, the fluid must be changed periodically, because no matter how high-quality the filter is, it will eventually become unusable. When draining the liquid from the pool, take a brush and try to clean the floor and walls of dirt. For this, various chemicals, which are designed to get rid of this kind of problem.

If the water still turns green, then drastic measures must be taken. Green water in the pool requires an integrated approach. It is not easy for filters to clear algae from a pool, and they are not able to do it completely. Therefore, chemicals are also used here.

First, you can try treating the pool liquid with chlorine. This method will be quite effective if there are not so many algae in the water, and the process of their reproduction is at an advanced stage. initial stage. But it is worth remembering that the use of chlorine can cause allergic reactions. Therefore, be careful and careful, and also remember that the concentration level of this chemical in the liquid should not exceed 3 mg per 1 liter of water.

You can work with other chemicals that are more effective and less harmful. These are algaecides. They are intended for effective disposal from fungus, mold and algae. These substances contain coagulants that quickly dissolve in water and envelop all existing dirt, bacteria or algae. Thanks to the resulting shell, such particles of treated dirt can be easily filtered and removed using a filter.

Pool water turns green: what to do

To make your relaxation in the pool a joy, maximum purity of the water is a prerequisite. To achieve this result, it is necessary to use some special water treatment products, because you can often encounter an unpleasant situation when the water in the pool turns green. Because of this tiles becomes slippery and covered with yellow-green spots. Moreover, mucus appears in the water, which makes staying in the pool completely uncomfortable.

If the pool is filled with untreated water, it can become a biologically favorable environment for the proliferation of various microorganisms. This process (when the water turns green) happens very quickly, and the unpleasant results of water deterioration appear just a few days after filling the pool. The first signs of an unpleasant phenomenon are that the water gradually turns green - its hue becomes green precisely because of the active activity of bacteria and algae. If no action is taken, the algae will become noticeable. However, there is another sign of spoiled water - in addition to a greenish tint, unpleasant odors also appear. The main reason leading to the appearance of a green tint is the entry of various microorganisms and fungal spores into the pool, which spread through the air. Once in a favorable environment, they begin active development, and a problem can be encountered not only when using an outdoor pool, but also an indoor one. The spores that cause pool water to turn green are found everywhere.

In order to eliminate the problem, some measures should be taken and the pool should be properly equipped. In particular, pool water preparation is required, that is, reliable and effective water filtration systems - without them, all other measures will not bring the desired long-term result. Crystal clear water can only be seen in a pool with a high-quality modern water purification and water treatment system, which will not allow the water to turn green. For example, with the help of a sand filter, all water can be freed from foreign impurities twice a day. If it is necessary to solve the problem with water that has already turned green, the optimal solution would be special chemical preparations belonging to the algaecide subgroup.

This type substances allows you to effectively solve the problem with unicellular algae, which are the main cause of water blooms. The drugs show good results in preventing the development of microorganisms in pool water. Of course, the use of chemicals must be timely, because if plant microorganisms have already developed significantly, the only way out of the situation will be a complete drainage of the water and a full-scale cleaning of the entire pool system, including using the indicated chemicals.

The use of disinfectants will avoid such a situation when the water in the pool turns green. However, they do not provide a 100% guarantee of results - chemical agents are not effective enough for some bacteria. In particular, it is not always possible to cope with some pathogenic bacteria, while their removal is one of the main reasons for disinfection. The most effective and proven solution to eliminating green water is the use of chlorine. It works quickly and is truly effective.

If measures are not applied in a timely manner, the use of chemicals and even softener filters will not be enough. You will have to completely drain the pool, rinse clean water with the addition of special chemicals, the entire structure of the pool, all pipes related to it. It is quite possible that mechanical cleaning of surfaces from algae will also be required. Only then can the pool be filled with water again. It must be taken into account that solving the problem of algae in swimming pools without the use of drastic measures is only possible if preventive measures are taken. These include the use of modern models of filters and chemical reagents that prevent the development of bacteria and algae, which cause the water in the pool to turn green.

causes and methods of solving the problem

Has the water in your pool started to bloom or turn green? Appeared bad smell? Don't know what to do in this case? Read the article and find answers to all your questions.

Causes and methods of elimination

If the water in the pool turns green, it is due to microorganisms and algae. A similar problem is typical for reservoirs with untreated water. Bacteria enter a favorable environment under the influence of sun rays and heat multiply, the smell and color of the liquid deteriorate.

Modern swimming pools are equipped with filtration systems. Water is driven by a pump through cartridges filled with cleaning compounds. But not everyone can afford to install such a system. However, the water may still turn green and acquire an unpleasant odor.

There are several methods of disinfection:

• algaecide preparations;
• hydrogen peroxide;
• chlorination.

The latter method is used less and less. The fact is that chlorine compounds, although they disinfect water, are harmful to human health. Even a slight overdose of the substance causes dry skin and gives a specific odor to the water. Therefore, within the framework of this article we will not consider chlorination.

How to Use Hydrogen Peroxide for Cleaning

Let’s make a reservation right away, we are talking about a 37% solution of hydrogen peroxide. Another name is perhydrol. The product sold at the pharmacy and used to disinfect wounds will not help in the pool.

The dosage of hydrogen peroxide for water purification is calculated based on the cubic capacity of the pool. For 1 m3 you need 700 ml of the drug. See the calculation of perhydrol using an example.

• pool length – 5 m;
• width – 3 m;
• depth – 1.8 m.

The cubic capacity is calculated using the formula V = L×W×D, that is, 5×3×1.8= 27 m3. To find out the dosage of hydrogen peroxide, multiply the cubic capacity by the amount of perhydrol for 1 m3. The result will be 18,900 ml or 18.9 liters. Many? Yes, but hydrogen peroxide is cheaper than algecides, so this method is more economical.

Application of algecides for water purification

If the manufacturer's instructions are followed, the drugs do not have any negative impact on human and animal health. Fungi, mold and protozoan algae are killed, which are the reason why the water blooms and acquires an unpleasant odor.

See the table for the list of drugs, their dosage and estimated cost.

Now you know what to do if the pool water turns green and how to fix the problem. Read the instructions for the medications carefully. The dosage may be different depending on the purpose of use and the type of pool.

The water in the pool turns green: what to do, how to deal with it

Pool on personal plot or in country house, performs several functions at once: it decorates the landscape, saves from the summer heat, and provides the body with the necessary water treatments. For children, joy; for adults, benefits and a solid list of associated problems, because you always have to pay for pleasure. Most often, pool owners are faced with a situation where the water, from bluish and crystal clear, turns into green turbidity in the literal sense of the definition. How is water purified in an outdoor pool?

Water is the key to life not only on the planet, but also in open-type pools, whether they are stationary or framed. Green water not only discourages anyone from splashing around, emits unpleasant odors and spoils the view, it is also dangerous to health, especially for children. Moreover, along with the color and smell, the walls of the pool become covered with a slimy substance, contact with which is fraught not only with unpleasant sensations, but also with the possibility of slipping out of the blue.

Common Causes

The amber and characteristic color appears near the water as a result of the development of microorganisms, this is not necessarily algae, there are many other representatives of underwater flora and fauna. Why does the pool water turn green quickly? There is a simple answer to this question.

Sunlight is an ideal catalyst for reproduction, spores are carried by air, and the nutrient substrate is generously supplied by bathers. Yes, human sweat, pieces of epidermis, dirt on the body and all our secretions are a wonderful nutrient medium. We have figured out the technology of the process, but there are several reasons for such a “blooming”, and this is how the swampy state of the pool is characterized.

• There is no filtration and circulation system, or the existing one cannot cope with the volume. If you skimp on filters and a pump or save money by installing weak, but cheaper ones, flowering will become a reliable companion.
• Disinfectants are not used or are used in smaller quantities. For most of us, the concept of chlorination is strongly associated with aggressive chemicals and all kinds of harm; many are simply afraid to use antiseptics. However modern compositions practically harmless to health, as they are designed taking into account all aspects of application.

For many summer residents who come to the site for the weekend, a “fragrant” artificial pond reminiscent of a swamp becomes an unpleasant surprise, and it does not matter whether it was covered with an awning before leaving. Therefore, instead of swimming, which you are looking forward to during the trip, you will have to worry about cleaning.

What to do

The method of dealing with greenery depends on the volume of the pool and the stage at which the owners grabbed it. If this is a children's inflatable container, the easiest way is to drain the water, clean the walls, bake it in the sun and fill it again. What if there are a dozen cubes in the pool, and each one costs money, and there’s a lot of hassle with a new set? Then draining is not the best and most affordable idea; it is easier to clean the container than to refill it. There are proven ways to combat flowering, since you haven’t bothered to prevent it. They consist of two types of influence.

• Disinfection.
• Recycle.

Disinfection

To carry this out, special preparations – algaecides – are added to the pool. They suppress the development of algae and other flora, but do not eliminate pathogens. Chlorine-containing products are used simultaneously with algaecides. Depending on the manufacturer, protective chemicals can be liquid, powder, granular or tablet.

The most important thing when using it is to adhere to the dosage based on the volume of the pool. If swimmers experience unpleasant sensations, it is worth reducing the dose or choosing a different complex. Tablets for disinfecting pool water - one of effective ways.

After adding the product to water, sediment or foam appears, which is removed during filtration. If the pool is neglected and the filters cannot cope, you can use a special bottom vacuum cleaner.

In the video - how to treat a pool so that the water does not turn green (how to deal with greening):

Recycling

A special system of filters and pumps is installed in the pool; during circulation, the water is purified and returned free of contaminants. The size of the particles that it takes from the water depends on the type of filter; modern, expensive devices are capable of cleaning to an almost ideal state. Here you can read how a pool sand filter works.

You can also use a vacuum cleaner to clean the pool.

Along with filtration, if there is a strong bloom, mechanical cleaning of the pool will be required. Technologies do not stand still, but they cannot do without brute physical force. A brush is the most effective means of cleaning the bowl from mucus, so the owner, household members or a called team will have to manually remove the plaque. And the pump and filters will remove the results of manual activity.

What to do to prevent symptoms

To avoid having to take breaks from swimming and regularly scrub the pool, you should take care of the problem of flowering in advance.

• Install filters and pump. This is possible at any stage of the pool’s operation.
• Use barrier chemistry. The compositions are used not once a season, but constantly, they are added as needed.
• Monitor the alkaline level. The notorious pH is important not only for dental health, but also for water. Special kits are available for swimming pools, which include indicator strips.
• Monitor the temperature of the water; when overheated, all processes accelerate.
• No one has canceled the need for regular mechanical cleaning, pick up the net and go.

The video shows preventive measures:

There are also traditional methods to combat flowering, many use algaecides instead copper sulfate, and antibiotics against bacteria. The link tells you how to add copper sulfate to your pool.

In addition to stationary filters mounted outside, there are also mobile ones. These are mobile or on-board skimmers that collect contaminants from the top layer. They are usually used in frame and inflatable pools.

On sale today latest developments, these are ultraviolet lamps, ozonizers and ionizers on silver or copper. They allow you to abandon chemical methods of water purification. However, with a lot of advantages, the main disadvantage of these gadgets is the exorbitant cost. Few people will decide to purchase a cleaning lamp, which is more expensive than the pool itself; it’s easier to change the water every few days. For summer residents, in general, great way, at the same time, the garden and vegetable garden are regularly watered. Just don’t try to use chlorinated water; you could lose all your plants at once.

It is easier to prevent water blooms than to deal with its consequences, but even if this is not done, cleaning the pool is not the most difficult procedure. The main thing is not to wait until the bowl is covered with mucus and an odor appears, but to carry out regular treatment. Also read how ponds are cleaned. Watch a video of cleaning a pool with hydrogen peroxide. You might be interested in the intex frame pool heater. For more information on how to heat water in a pool at your dacha, see here.

Having your own swimming pool has long ceased to be a luxury, but has acquired the status of a mandatory attribute. But its operation requires certain work that must be carried out without fail, as well as monitoring the condition of the water. Cloudy water in the pool, the appearance of an unpleasant odor, or the appearance of a greenish tint indicate that it is time to take action. In order for the water not to turn green and to be clean and transparent, you should know the reasons for the deterioration of its quality and how to combat them.

Reasons

The water in the pool turns green and blooms when it begins to large quantities various harmful microorganisms and algae appear and multiply. Their life process is accompanied by the appearance of an unpleasant odor and greening. Under the influence of sunlight, the processes of reproduction of bacteria and viruses occur more intensely. At the same time, bathers constantly supply them with nutrition, in the form of sweat and secretions, epidermis and existing dirt on the surface of the body.

The water in the pool becomes cloudy and green for the following reasons:

• Presence of algae. The volatile spores of these microorganisms are quite tenacious and can spread over vast distances. They are not afraid of climate change, and the most favorable environment for their life is the warm water that fills the pools; ​Attention! The spread of algae in indoor pools is much slower, but the water in them is also susceptible to blooms and cloudiness.
• Poor filtration and water circulation. Standing water in the tank, infrequent replacement of filter elements, malfunction or absence of pumps contribute to the faster spread of microorganisms;
• Imbalance of chemicals in aquatic environment. To prevent the water in the pool from turning green and becoming cloudy, chlorine-based products and algaecides are used. If the balance of water is at an inappropriate level, then their use is ineffective; Attention! The chlorine level in the water should be between 0.3 mg and 0.6 mg, but should not exceed 2 mg. In this case, the pH level for the pool should be in the range from 7.0 to 7.4. One of the options for devices that help determine chlorine and pH levels is shown in the video
• Water stabilization level. The main component, which is a stabilizer and is present in many chlorine-based products for water purification in swimming pools, isocyanuric acid, which inhibits the decomposition of chlorine under the influence of sunlight. But its accumulation contributes to the complete cessation of the effect of chlorine, and the water becomes over-stabilized. Such water in the pool will definitely bloom, somewhere in the middle of the season, so it is recommended to completely or partially drain it and fill the pool tank with new water;
• Excess iron. Green water in the pool it becomes from algae, and if it is transparent, but there is a greenish or brown tint in it, then the reason lies in an excess amount of minerals - iron. To eliminate this problem, you should use coagulants for cleaning.

In addition to the reasons listed, the water may become bloomy and cloudy in the following situations:

• Long period of inactivity of the pool;
• Insufficient amount of sunlight;
• Garbage carried by the wind;
• Inappropriate and insufficient mechanical cleaning;
• Incorrectly calculated doses of chemicals and cleaning agents.

As a rule, to prevent the water in the pool from blooming, it is a good idea to regularly clean the inner coating. The first signs of beginning flowering are:

• Slippery walls and bottom;
• The appearance of foam on the surface of the water;
• The appearance of an unpleasant odor.

Remedies

There are many ways to make a green pool safe and usable. All of them can be divided into the following:

• Mechanical;
• Chemical;
• Electrophysical.

Mechanical cleaning methods

One of the methods of mechanical cleaning is the installation of filter elements.

These units are capable of efficiently cleaning the pool from small particles of dirt and dust, trapping harmful microorganisms, but do not help against algae spores. Those filters that are capable of retaining spores are quite expensive, require increased attention and constant replacement of filter consumables, and still do not give a sufficiently high-quality result.

One more mechanically cleaning the pool is to use a net. It removes visible algae spores. Also, simple mechanical cleaning involves emptying the container of water and simply washing the walls and floor.

Chemical cleaning methods

For chemical cleaning special preparations are used - algaecides. Their peculiarity is that they are safe for human health, but have a negative effect on mold, mildew and algae, as well as other harmful microorganisms.

Depending on the manufacturer, algaecides come in different forms– tablets, granules, powder or liquid substance.

Another chemical method of disinfecting pool water is chlorination. When using special chlorine-based preparations, work should be carried out very carefully, since excess chlorine is unsafe for humans.

Electrophysical cleaning method

To prevent water from blooming, turning green and becoming cloudy, special devices and equipment are used as an electrophysical method of purification. One of these is an ozonizer. The operating technology of such a device is discussed in the video:

Traditional cleaning methods

There are also traditional methods of purifying pool water that will help you cope with cleaning without the use of expensive products and devices:

Conclusion

Having familiarized yourself with the cleaning methods, you can safely answer the question of what to do if the water in the pool turns green. The main thing is not to let it get into a neglected state, but to start acting at the first signs of contamination. And then the artificial reservoir on the site will always delight you with its cleanliness, and will provide a portion of pleasant emotions on the hottest day.

If the pool water turns green

There is no better relaxation than swimming in your own pool. This kind of relaxation requires crystal clear water. However, many have probably seen how the water in the pool turns green. The walls and bottom of the pool become slippery, and persistent yellow-green stains form. It's even worse when, while shopping, you find mucus residue on your body. What to do in this case, how to overcome such an unpleasant phenomenon? Let's look at this in more detail.

Why does the water turn green?

When a pool contains untreated water, it represents a biologically favorable environment in which various microorganisms will certainly multiply over time. After just a few days, the walls of your pond will be covered with thick mucus. You will notice that the water turns green (takes on a green tint). Such facts indicate the active activity of bacteria and excessive growth of algae.

It is because of them that an unpleasant odor and a greenish tint appear inside your font. You can see this shade in many bodies of water. Its main cause is numerous spores of fungi and algae spreading through the air. Once in a body of water, they begin to develop very actively in it. That's when they say the pool blooms. It makes no difference where exactly the reservoir is located - indoors or outdoors.

Spores of such organisms are everywhere. You can conduct a small experiment: pour a little water into a container, leaving it in open form. After a couple of weeks, you can see that this water has turned green - it is blooming. If you do not take any action, then the water inside the pool will also turn green, and its walls will be covered with a yellow-green coating. How to deal with this?

What to do if the pool is blooming?

Eliminating algal blooms is not that difficult. Good filtration in combination with proper disinfection completely frees the pool from blooms: without these two components, the fight against blooms in the pool will be ineffective. To truly make your water crystal clear, you should install a modern pool filter. It is necessary to set the operating time of the sand filter so that the entire volume of pool water passes through it at least twice a day. When disinfecting, if the water in the pool is blooming, emphasis should be placed on the use of special chemicals of the algaecide subgroup (desalgin, algitine and others).

Such substances reliably prevent the development of algae inside the reservoir, which causes water blooms. These drugs are used to fight algae or fungi. It is important to start using algaecides in a timely manner to avoid the development of plant organisms. If applied in advance, you will not need to clean the pool walls from unpleasant deposits.

When using such a disinfectant, keep in mind that it removes algae and does not harm bacteria. In addition, truly dangerous microorganisms remain in the pool and multiply vigorously. Moreover, they are invisible to humans. They will leave the water clear, but unsafe for health. To fight such an invisible enemy, use disinfectants. The most effective way to combat microorganisms living in pool water is chlorine, which provides rapid disinfection (we recommend drugs: chlorifix, complita, chlorilong, multilong, varitab, chloriclar, chloritex, chloroxone, longafor).

To combat both algae and bacteria great value has the temperature of the water in the pool: at temperatures above 28-30°C, the rate of reproduction of microorganisms increases significantly, and the risk of water bloom increases many times.

Muddy, green, blooming water is the main problem of all pools in suburban areas of our planet. Especially in the heat: before you have time to look back, instead of clear, light blue water, there is some kind of cloudy broth sloshing around in the pool. This article tells you what to do to prevent the water in your pool from blooming, and what emergency measures to take if the water does bloom.

Why does the pool water turn green?

In the water of an outdoor pool, well heated by the sun, ideal conditions for the development of various microorganisms. Most of them are safe for humans, but it is because of them that the water turns green, becomes cloudy and becomes covered with a film. Therefore, the task of the pool owner is to make these ideal conditions unbearable.

If the water in your pool is green, it means that:

• the filtration system does not work well enough or does not exist at all;
• the filter is not cleaned in time, traps cyanobacteria and they multiply directly in it;
• disinfectants are either not used, or used incorrectly, or in insufficient quantities - and there is no point in a minimum dose of chlorine;
• it's also possible chemical pollution. If chlorine-containing pool products contain excess cyanuric acid, it breaks down the chlorine and causes algal blooms in the water. There is nothing you can do to help here - the water will have to be drained;
• Pool water can also bloom from excess iron. In this case, it is green, but transparent and does not have an unpleasant odor.

I use artesian water, therefore not chlorinated, the microflora develops at a frantic pace. 5-7 days and the water becomes cloudy and green, mosquitoes and all sorts of waterfowl bugs appear.

F_A_I FORUMHOUSE Member

It took 20 hours to pump 11 tons of water from a well. After two weeks the water turned green.

This problem can be successfully solved by using an integrated approach.

• constantly remove contaminants from the water with a net;
• destroy cyanobacteria with chlorine (or perihydrol);
• For effectiveness, add a product that destroys the bacterial membrane.

No matter how much we would like to avoid “all kinds of chemicals,” the water in the pool must be disinfected. There's nothing wrong with that. Modern water disinfectants in the correct dosage are safe for humans.

What to do if the pool water turns green

In order for pool cleaning products to work effectively even in small doses, you need to constantly monitor the hardness of the water in it. In general, water hardness values ​​are the first thing you need to find out if you have acquired a swimming pool in a suburban area.

Logvin FORUMHOUSE member

Chlorine and PH tests are at your fingertips.

If the values ​​are below 7.2, then this is fraught with corrosion of the metal parts of the pool. If the pH is above 7.6, swimming in the pool may be dangerous and may cause irritation to the eyes and mucous membranes. At such a pH, lime will settle to the bottom of the pool, and the worst thing is that in such incorrect water the chemistry works much worse or does not work at all. You can do everything according to the instructions, but the water will still remain green.

Therefore, the pH value must be monitored all the time.

What to do to prevent the water in the pool from turning green

So, this is how we need to proceed from the day we fill the pool so that the water in the pool always remains clear:

• find out the degree of water hardness. If the pH level is up to 8 degrees. DH, inorganic chlorine can be used for disinfection, although experts recommend always choosing organic chlorine compounds.
• for prevention, before filling the pool with water, wash its walls with an algaecide solution in a ratio of 1:25. (Algaecides are herbicides that break down the cyanobacteria and actually kill the algae. They sound scary, but they are not nearly as dangerous as the herbicides used in agriculture. Available in tablets or liquid form).
• fill the pool with water.
• run the filter. It is recommended to rinse the sand filter once a week to wash away dirt between grains of sand, prevent the appearance of channels and sand crust at the bottom of the filter, and loosen the sand.
• evenly distribute as much algaecide on the surface of the water as indicated in the instructions.
• measure the pH value with a testing device.
• using reacting acid granules, “pH-plus” or “pH-minus”, ensure that the pH level is 7.2-7.6. How to do: Sprinkle the granules evenly over the surface of the water in small portions, and check the pH level after each portion. Approximately, to increase the pH by 0.1, pour about 100 g of pH-plus per 10 cubic meters of water; to reduce pH by 0.1, pour 100g pH-minus per 10 cubic meters of water. If the water is hard, product consumption increases. It is highly recommended to maintain a pH level of 7.2-7.6
• Disinfect the water by adding chlorine. Only when there is a constant excess of chlorine in the pool water of 0.3 to 0.8 mg/l can we assume that complete sterilization has been achieved. Complete sterilization of water is guaranteed with a constant excess amount of chlorine from 0.3 to 0.8 mg/l.

For disinfection, FORUMHOUSE participants use different means, from ordinary “Whiteness” to “long-term chlorine” tablets.

In order not to bother with anything, they came up with long-term chlorine. Today, bass maintenance is reduced to throwing long chlorine tablets. For prevention, you can add a little algaecide. ALL! Make sure that the pH is normal and nothing else is needed.

• Check the amount of chlorine in the water with a testing device, add more if necessary. Follow the manufacturer's recommendations.

Pool chemicals used by FORUMHOUSE members

In the fight against muddy water, users of our portal use:

Pool water care systems like “three in one” work well, for example, Algaecide, supplemented with long-term chlorine.

Also, the pool owner’s personal set of chemicals must include:

• good product for cleaning pool edges;
• powerful cleaners that destroy bacteria during general pool cleaning;
• products that are added to the pool before storing it for the winter.

You need various thermometers for measuring water temperature, testers showing the CL content and PH value, dispensers-floats for large “long chorus” tablets.

How to solve problems

If you follow the above rules, there should be no problems with water in the pool. But if they appear, the situation can almost always be corrected.

Perhydrol, or Tair's method

To disinfect pool water, instead of chlorine, many use perhydrol (hydrogen peroxide in large dosages). This method, which has won popular love, was discovered by a FORUMHOUSE member with the nickname Tair.

Having your own swimming pool has long ceased to be a luxury, but has acquired the status of a mandatory attribute. But its operation requires certain work that must be carried out without fail, as well as monitoring the condition of the water. Cloudy water in the pool, the appearance of an unpleasant odor, or the appearance of a greenish tint indicate that it is time to take action. In order for the water not to turn green and to be clean and transparent, you should know the reasons for the deterioration of its quality and how to combat them.

Reasons

The water in the pool turns green and blooms when various harmful microorganisms and algae begin to appear and multiply in large quantities. Their life process is accompanied by the appearance of an unpleasant odor and greening. Under the influence of sunlight, the processes of reproduction of bacteria and viruses occur more intensely. At the same time, bathers constantly supply them with nutrition, in the form of sweat and secretions, epidermis and existing dirt on the surface of the body.

The water in the pool becomes cloudy and green for the following reasons:

• Presence of algae. The volatile spores of these microorganisms are quite tenacious and can spread over vast distances. They are not afraid of climate change, and the most favorable environment for their life is the warm water that fills the pools; ​Attention! The spread of algae in indoor pools is much slower, but the water in them is also susceptible to blooms and cloudiness.
• Poor filtration and water circulation. Standing water in the tank, infrequent replacement of filter elements, malfunction or absence of pumps contribute to the faster spread of microorganisms;
• Imbalance of chemicals in the aquatic environment. To prevent the water in the pool from turning green and becoming cloudy, chlorine-based products and algaecides are used. If the balance of water is at an inappropriate level, then their use is ineffective; Attention! The chlorine level in the water should be between 0.3 mg and 0.6 mg, but should not exceed 2 mg. In this case, the pH level for the pool should be in the range from 7.0 to 7.4. One of the options for devices that help determine chlorine and pH levels is shown in the video
• Water stabilization level. The main component, which is a stabilizer and is present in many chlorine-based products for water purification in swimming pools, isocyanuric acid, which inhibits the decomposition of chlorine under the influence of sunlight. But its accumulation contributes to the complete cessation of the effect of chlorine, and the water becomes over-stabilized. Such water in the pool will definitely bloom, somewhere in the middle of the season, so it is recommended to completely or partially drain it and fill the pool tank with new water;
• Excess iron. Green water in the pool comes from algae, and if it is clear, but there is a greenish or brown tint in it, then the reason lies in an excess amount of minerals - iron. To eliminate this problem, you should use coagulants for cleaning.

In addition to the reasons listed, the water may become bloomy and cloudy in the following situations:

• Long period of inactivity of the pool;
• Insufficient amount of sunlight;
• Garbage carried by the wind;
• Inappropriate and insufficient mechanical cleaning;
• Incorrectly calculated doses of chemicals and cleaning agents.

As a rule, to prevent the water in the pool from blooming, it is a good idea to regularly clean the inner coating. The first signs of beginning flowering are:

• Slippery walls and bottom;
• The appearance of foam on the surface of the water;
• The appearance of an unpleasant odor.

Remedies

There are many ways to make a green pool safe and usable. All of them can be divided into the following:

• Mechanical;
• Chemical;
• Electrophysical.

Mechanical cleaning methods

One of the methods of mechanical cleaning is the installation of filter elements.

These units are capable of efficiently cleaning the pool from small particles of dirt and dust, trapping harmful microorganisms, but do not help against algae spores. Those filters that are capable of retaining spores are quite expensive, require increased attention and constant replacement of filter consumables, and still do not give a sufficiently high-quality result.

Another mechanical way to clean a pool is to use a net. It removes visible algae spores. Also, simple mechanical cleaning involves emptying the container of water and simply washing the walls and floor.

Chemical cleaning methods

For chemical cleaning, special preparations are used - algaecides. Their peculiarity is that they are safe for human health, but have a negative effect on mold, mildew and algae, as well as other harmful microorganisms.

Depending on the manufacturer, algaecides come in different forms - tablets, granules, powder or liquid.

Important! When using algaecides, the dosage specified by the manufacturer should be strictly followed.

Another chemical method of disinfecting pool water is chlorination. When using special chlorine-based preparations, work should be carried out very carefully, since excess chlorine is unsafe for humans.

Electrophysical cleaning method

To prevent water from blooming, turning green and becoming cloudy, special devices and equipment are used as an electrophysical method of purification. One of these is an ozonizer. The operating technology of such a device is discussed in the video:

Traditional cleaning methods

There are also traditional methods of purifying pool water that will help you cope with cleaning without the use of expensive products and devices:

Conclusion

Having familiarized yourself with the cleaning methods, you can safely answer the question of what to do if the water in the pool turns green. The main thing is not to let it get into a neglected state, but to start acting at the first signs of contamination. And then the artificial reservoir on the site will always delight you with its cleanliness, and will provide a portion of pleasant emotions on the hottest day.

What to do if the water in the pool is blooming?

Home » Country houses.

Has the water in your pool started to bloom or turn green? Got an unpleasant odor? Don't know what to do in this case? Read the article and find answers to all your questions.

Causes and methods of elimination

If the water in the pool turns green, it is due to microorganisms and algae. A similar problem is typical for reservoirs with untreated water. Bacteria enter a favorable environment, multiply under the influence of sunlight and heat, and the smell and color of the liquid deteriorate.

Modern swimming pools are equipped with filtration systems. Water is driven by a pump through cartridges filled with cleaning compounds. But not everyone can afford to install such a system. However, the water may still turn green and acquire an unpleasant odor.

There are several methods of disinfection:

• algaecide preparations;
• hydrogen peroxide;
• chlorination.

The latter method is used less and less. The fact is that chlorine compounds, although they disinfect water, are harmful to human health. Even a slight overdose of the substance causes dry skin and gives a specific odor to the water. Therefore, within the framework of this article we will not consider chlorination.

How to Use Hydrogen Peroxide for Cleaning

Let’s make a reservation right away, we are talking about a 37% solution of hydrogen peroxide. Another name is perhydrol. The product sold at the pharmacy and used to disinfect wounds will not help in the pool.

The dosage of hydrogen peroxide for water purification is calculated based on the cubic capacity of the pool. For 1 m3 you need 700 ml of the drug. See the calculation of perhydrol using an example.

• pool length – 5 m;
• width – 3 m;
• depth – 1.8 m.

The cubic capacity is calculated using the formula V = L×W×D, that is, 5×3×1.8= 27 m3. To find out the dosage of hydrogen peroxide, multiply the cubic capacity by the amount of perhydrol for 1 m3. The result will be 18,900 ml or 18.9 liters. Many? Yes, but hydrogen peroxide is cheaper than algecides, so this method is more economical.

Application of algecides for water purification

If the manufacturer's instructions are followed, the drugs do not have a negative impact on human and animal health. Fungi, mold and protozoan algae are killed, which are the reason why the water blooms and acquires an unpleasant odor.

See the table for the list of drugs, their dosage and estimated cost.

Now you know what to do if the pool water turns green and how to fix the problem. Read the instructions for the medications carefully. The dosage may be different depending on the purpose of use and the type of pool.

The water in the pool turns green - what to do?

People who have a swimming pool may experience blooms in the pool water. This happens to everyone, the only question is time. There are many special products that are designed specifically for water disinfection, but, no matter what, dealing with the problem of green water and its unpleasant odor is very difficult.

The reasons why the process of blooming of basin water occurs

The pool is a very good breeding ground for various microorganisms. There are many factors that contribute to this:

Ways to eliminate green water in the pool

If the water in the pool turns green, then what should you do? It is necessary to understand that the products that can be purchased on the market are effective, but only for a while. But, nevertheless, when water blooms, it is necessary to take other measures in addition to chemicals. There can be many reasons for flowering, so the approach to this problem should be comprehensive.

But still, why does the water in the pool turn green? The main reason for this phenomenon is that brown and green algae bloom. Their spores move through the air into the water, and their active growth occurs.

To eliminate this problem, you can treat the liquid with chlorine. You can also use special preparations called algaecides instead. They, unlike chlorine, cannot cause allergic reactions, but, accordingly, their cost is higher. If the water turns green due to lack of circulation, then this cause can be eliminated and the water will become normal again. If you use chlorine, then you need to know that its standards should not go beyond sanitary and epidemiological limits, that is, not exceed 3 mg per liter.

There are other methods of water disinfection - the use of ultraviolet light and ozonation. These options are very highly effective, but they are not used often.

Ozonizers have a very high cost, so few people can afford to buy them, and ultraviolet lamps are not profitable to use from an economic point of view, especially if the pool is large.

Stages of the blooming water purification mechanism:

• Preliminary protection is needed;
• Blooming water must be filtered;
• The use of special means that prevent the proliferation of harmful microorganisms.

Let's try to understand each stage in more detail.

Preliminary protection

If you use water to fill your pool that already contains microorganisms (that is, water from a reservoir or rainwater), then you need to put in a lot more effort to clean it. It is very good if there is an awning or a protective cover. After all, these things can prevent access to sunlight and debris. If such a cover is not available, then you need to try to do everything possible to purchase it. A cover or awning is not expensive.

Water filtration

You need to know the fact that throughout the day an amount of water corresponding to two to three volumes of the pool should pass through the filter. If it spends more, then this is a definite plus. Basically, all pools are equipped with a filter and pump. They can be combined in one case, but this is already in inexpensive models. If the filter operates with sufficient power, the water bloom will not be so intense. You can calculate how long a day the pump should run. For convenience, you can use automatic timers.

The use of agents that prevent the proliferation of microorganisms

When there is algal bloom in the pool, be sure to use an anti-algal bloom remedy. The best option is to contact special services involved in pool maintenance and water treatment. After taking a water sample and analyzing it, they will be able to determine the most effective remedy to correct the problem. If measures are not taken in a timely manner, it will be necessary to drain the pool and rinse it with water saturated with special chemicals. If there is algae, then you need to carry out mechanical cleaning. Only after such measures can water be released into the pool again.

What to do if the pool water turns green

A swimming pool, especially one located outside, brings special pleasure to its owners, especially during periods of elevated temperatures. The water in it provides an excellent opportunity to refresh yourself without leaving your home. But, like everything that surrounds us, the pool, and especially the water, requires special care and maintenance. The garbage that the wind brings and we leave behind, various types of pollution, bacteria, as well as the process of water blooming - these are the problems that should be dealt with.

If debris and dirt can be easily dealt with by cleaning the pool or changing the water, then green liquid is a real problem. Why does it occur?

Flowering of the water surface occurs especially actively in the warm season. This process is caused by the proliferation of special microorganisms, namely green and brown algae. They are not like the algae we are used to. These are microscopic organisms that reproduce at an incredible rate and densely cover the bottom and walls of the pool. The reproduction process occurs in an ideal environment for them:

• Humidity;
• Sufficient sunlight;
• Warm;
• “Food” - leaves, debris and anything that can get into the pool serves as a good treat for these microorganisms.

Such an environment is more than conducive to water blooming, and this process is just a matter of time if appropriate measures are not taken.

In order to prevent the flowering process, it is necessary to ensure that the liquid in the pool is always as clean as possible. To do this, you need to install a filter in the pool. It will help maintain the required level of cleanliness in the pool. In addition, the fluid must be changed periodically, because no matter how high-quality the filter is, it will eventually become unusable. When draining the liquid from the pool, take a brush and try to clean the floor and walls of dirt. For this, various chemicals can be used that are designed to get rid of this kind of problem.

People who have a swimming pool may experience blooms in the pool water. This happens to everyone, the only question is time. There are many special products that are designed specifically for water disinfection, but, no matter what, dealing with the problem of green water and its unpleasant odor is very difficult.

The pool is a very good breeding ground for various microorganisms. There are many factors that contribute to this:

• Presence of organic matter. If the pool is located outside, leaves and other debris may fall into it. All this is excellent food for microorganisms.
• Warm. Bathing requires warm water, and it is excellent for the growth of algae and bacteria.
• Light. Algae need it.
