POOL MANAGEMENT

You do not have to be a chemist to keep the water in a pool clean. It is enough to have a basic knowledge of the values of the pool water in order to intervene with the right products. Periodically analyzing the parameters prevents the occurrence of algae and melmosity in the pool that can cause fungal and bacterial infections. The filtering system plays an important role in retaining the impurities of the pool but unfortunately it is not able to eliminate the bacteria. For this reason it is necessary to add chlorine or iodine disinfectants.


FUNDAMENTAL VALUES TO RESPECT

VALUE OF PH

The pH parameter must be between 7.2 and 7.6. If the pH value is less than 7.0, the water is acidic and the pH value must be raised with the use of pH+, if the pH is above 7.6, the water is basic, therefore it should be decreased with the use of pH-. Generally the pH tends to increase over time: it increases rapidly with the use of alkaline chloride products (hypochlorites).


VALUE OF FREE CHLORINE

The free chlorine is that quantity of chlorine present in the water and not yet bound for which the disinfecting power is active; The value of free chlorine must be between 0.6 ppm and 1 ppm and must be uniform at any point in the tank. Keep in mind that chlorine reactions are possible when the pH value is between 6.5 and 8.
 

VALUE OF COMBINED CHLORINE
The combined chlorine is that amount of chlorine that combines with organic and inorganic pollutants containing nitrogen (skin residues, sweat, urine, etc.); For good bathing the combined chlorine value must be lower than 1 ppm, and it must be uniform at any point in the pool; The combined chlorine excess is the main reason for the classic "chlorine smell" present in certain pools, compared to free chlorine, the combined chlorine is active even in a reduced percentage.



VALUE OF TOTAL CHLORINE
Total chlorine is the sum of the value of free chlorine and the value of combined chlorine; The total chlorine value must be less than 1.50 ppm and must be uniform at any point in the pool.

ALKALINE VALUE
The alkaline value must be between 125 ppm and 150 ppm. If the alkalinity values are not between 125 and 150 ppm, the pH will fluctuate and will not be able to stabilize.

CHIANURIC ACID VALUE

The cyanuric acid is found in granular chlorine and it is used as a binder to avoid easy evaporation. In addition to making the action of chlorine constant, over time, cyanuric acid tends to concentrate, so much so that chlorine identify it as an organic agent and neutralizes it. The value of cyanuric acids must be between 25 and 50 ppm; The only way to eliminate excess cyanuric acid is to change the water.
 

HARDNESS VALUE
The set of salts dissolved in water is referred to as hardness. The hardness value should be between 200 ppm (20° F) and 400 ppm (40° F).
