Prepare the water for the swimming pool!

For example, a "chemical" element as chlorine is considered to be harmful, but there are useful oxygen - in fact, not at all "chemical" component.Let's try to understand all this.

Sodium chloride, better known as table salt we eat every day.This essential product contains chlorine, but it really does not smell.Where did the opinion that chlorine has a sharp unpleasant smell?Let's start with the fact that the pool water is disinfected with chlorine are not, but with the help of hypochlorous acid, which is almost no smell.For comparison, a bottle of smell "whiteness."It chlorine 10 thousand times greater than that required to effectively purify the water in the pool.In fact, the sharp smell are chloramines, which with proper disinfection should not even be in the water.

What is pollution must be fought throughout the season to keep the pool clean?

1. Leaves, sand, dust, etc.They can handle the filtration system.If you do not want to change the water every day, such a system is required to be purchased


2. Contamination of organic origin such as sweat, urine, etc.These substances are already struggling with the help oxidants.Good oxidants are chlorine and hydrogen peroxide, the latter - is stronger at 30% chlorine.

3. Pathogens.By getting rid of germs and bacteria using disinfectants .Well disinfects chlorine.Hydrogen peroxide has a very slight disinfecting effect.To remedy worked, it is necessary to use at concentrations 100 times greater than in the case of chlorine.

4. Algae.It is this polluter first makes the water turbid, then it starts to turn green.Get rid of the algae will also help to more concentrated disinfectant.It is necessary to "break" a kind of a protective film, which is covered with the aquatic plants.Against algae used algaecides.However, using only these substances, chlorine-free, you get clear water, but full of harmful microorganisms.

Filtration (water treatment mechanically)

Without filter in the pool can not do.During the day, all the water must pass through the filter element is least two times, and with increasing load of the pool - at least three.


most commonly used to disinfect swimming pools products containing chlorine.If applied properly, the water will become odor.Avoid drugs that help alternative to chlorine, but with some reservations.

1) Active oxygen

Otherwise, it is called potassium peroxymonosulfate.This tool does not contain chlorine, but operates at least two hours, and then decomposes.Its use is recommended once every five days.So all this time (except for the time of the drug) bacteria will breed in the pool.

Foreign experts potassium peroxymonosulfate used only as a shock means for cleaning overgrown pools.So for disinfection this drug is not suitable .

2) Bromine

This drug does not have the chlorine smell, but not without flaws.First - this is its higher cost.Bromine release tablets that dissolve slowly in special, expensive storage devices - bromatorah.The second "a minus" - chemical smell of the drug.Another - for effective disinfection requires higher than chlorine concentration.Poor and what it means is decomposed by ultraviolet rays.Chlorine is also characteristic of this problem, but it is solved by a stabilizer, slow this process.But there is a stabilizer for bromine.Conclusion - this medication can not be used for swimming pools, which are open-air.

3) Chlorine

used to disinfect swimming pools are not chlorine and hypochlorous acid (the latter, a common name - "free chlorine").This drug has not sharp and mild odor.Most likely, you will not even notice it.Why are public swimming pools have the typical "hospital" smell?- You ask.The fact that the chloramines are well smell (or "combined chlorine") - products of incomplete digestion of organic matter of hypochlorous acid.If the pool is handled correctly, chloramines in the water appear.

Usually the appearance of combined chlorine due to a lack of free chlorine.To split the combined chlorine, you need to increase the concentration of the free.In other words, the chlorine odor can be removed by adding chlorine.Free chlorine in the pool to be used with sufficient but not low concentrations.If the water in the pool beginning to smell bad, then, reducing the concentration of chlorine, you will further strengthen the smell.

Thus, chlorine copes with all tasks that are assigned to the chemicals for swimming pools:

  • it oxidizes and destroys organic pollutants;
  • effective against pathogenic bacteria and microbes;
  • destroys algae.

A disadvantage of chlorine we have already mentioned: it quickly disintegrates when exposed to sunlight.If the pool does not use any stabilizer, about half of the free chlorine disintegrate in about 35 minutes.This solves the problem of drug called cyanuric acid.It protects against UV chloro yet reduces loss.However, this method of protection is a "downside" - anti-drug binds the chlorine and thus weakens its disinfectant properties.When using a stabilizer, the desired level of chlorine in the pool will be higher than in the pool, wherein no stabilizer is used.However, this should not be afraid.Excess chlorine "bind" cyanuric acid, and thus creating a sort of reserve.

Measurement of pH value ( pH )

For this we need a tester.Just say that the use of test strips, the work that resembles a child's game, it is not necessary.Stocks of more reliable means - test suite «Pooltester ph / Cl». It measures the pH, and at the same time - the content of free chlorine.

If the tester shows that the level pHv pool less than 7.2, is wary: such water can cause eye irritation.pH less than 6.8 may damage even metal parts.However, when more than 7.8 elevated pH-, calcium deposits can occur.Recommended level of pH - up to 7.4.At higher rates of hydrogen chlorine loses its disinfectant action.However, this rule applies only to water, which does not use a stabilizer.If there is such a drug, chlorine disinfectant retains characteristics even at higher rates of pH.

In most pools ph level over time increases.Aeration Basin - fountains, whirlpool and action games - also increase the hydrogen indices.Increase ph and with a special preparation - «Benamin pH-Plus».

To reduce this ph, drug use «Benamin pH-Minus».

So, the pH adjusted, and we can begin to chlorinate the water.

For long-term disinfection of water used means « Benamin Lang» .It destroys organic matter that causes turbidity in the open basins - opposes the growth of microspores green plankton, as well as providing clarifying effect.The special chemical composition and specific manufacturing methods «Benamin Lang» allow to dissolve tablets in the pool for a long time - from a week to two.This depends on the hardness and temperature of water.Gradually dissolving all this time, «Benamin Lang» daily nourishes the pool water a predetermined amount of active chlorine - it goes exactly as much as you need to disinfect water in the pool a certain volume.The tablets are placed in avtohlorator (if it is not - in the skimmer or dispenser "floating float").This frees you from having to add water necessary dose of chlorine every day.Just put in the skimmer as tablets, as required, and a week later when they are completely dissolved, replace with new!

Struggling with algae

blue-green algae, or in a scientific way - cyanobacteria - one of the oldest organisms on the planet.The pool for them are excellent conditions for life and reproduction.These algae health hazards are not, but agree that swim in murky green slush - not a pleasant one.

To cope with this problem, use substances that kill cyanobacteria - algaecides.The best algaecide considered again again, chlorine.To combat algae use a more concentrated composition of chlorine than is necessary to kill bacteria.Still, the amount is small and will not cause any discomfort when bathing.

what is sold as "algaecide" properly called "algistatami", iesubstances that impede the growth of algae.How do they work?As mentioned, a kind of seaweed coated with a protective film, which impairs the operation of disinfecting agents on the algae.Algaecides not destroy cyanobacteria, but only "wash" them with this protection and thus allow the disinfectant to make his case.

does not make sense to use a higher dose of algaecide to clear completely overgrown pool.Algaecide - a support tool that enables a shock dose of chlorine to cope with the problem.If you maintain the necessary level of chlorine in the pool, then the need for algaecides will be less than they are not destroyed with ultraviolet light, and keep them constant concentration difficult.
