Chlorine consumption varies with temperature, solar incidence, number of bathers and the degree of pollution. For these reasons, it is necessary to analyze the chlorine level daily with the help of a pH and Chlorine Analysis Kit .

The air, bathers and the surrounding environment continually introduce dirt into the pool water. This dirt causes cloudiness and serves as food for bacteria and algae. Therefore, it is necessary to eliminate it with the help of filtration equipment. The filter retains dirt particles from the pool water, keeping it transparent and crystal clear. It is important that the filter works in good condition and that the entire volume of water in the pool is filtered at least once a day.

4. Pool start-up

At the beginning of the season, the pool must be started. It is important to follow the proper procedure to avoid problems during swimming season.

1. Check that your pool equipment ( pump , filter , etc.) works correctly.
2. If necessary, empty the pool and clean the tank with CTX-51 Surface Descaler. Cleaning should be carried out when the sun is low, keeping the walls and bottom damp. Apply CTX-51 Surface Descaler. Then, leave the product to act for half an hour and then rinse with water.
3. Once the tank is clean, fill the pool.
4. Carry out shock chlorination with CTX-200/GR Granulated Dichlorine (15 g/m ³ of water) or with CTX-250 Rapid Chlorine Tablets (2 tablets/m ³ of water). If your pool takes more than a day to fill, it is recommended to dose it with CTX-200/GR Dichloro Granulado or CTX/GR 250 Rapid Chlorine Tablets during operation, to prevent algae formation.
5. Analyze the pH of your pool and, if necessary, adjust it between 7.2-7.4 with CTX-10 pH Lowerer or CTX-20 pH Increaser .
6. Start the maintenance program.

5. Water pH

pH indicates the acidity or basicity of the water. In a swimming pool, it should be adjusted between values ​​of 7.2-7.4. This interval, in addition to keeping the installation in excellent condition, is ideal for bathers' skin and eyes.

To keep it between these two values, analyze the pH daily with a chlorine and pH analysis kit. If the pH is higher than 7.4, add CTX-10 pH Lowerer to the water. If the pH is below 7.2 add CTX-20 pH Booster to the water.

6. Algae prevention

Algae are unicellular plant organisms that can develop and multiply quickly in water, especially when the temperature is temperate.

Algae spores are introduced into pool water through wind, rain, etc. To prevent its development, in addition to the disinfectant, an algaecide CTX-60 must be used.

7. Maintenance program

Daily

1. Analyze the pH of the water and adjust it between 7.2 - 7.4 if necessary.
2. Analyze the Free Residual Chlorine level, keeping it between 0.5 - 2 ppm. If you use a doser, adjust it to maintain this residual chlorine.
3. Remove existing leaves and insects from the water.

Weekly

1. Clean the skimmers and brush the tank walls. Then use the vacuum cleaner.
2. Backwash the filter, clean the pump pre-filter and empty the basket.
3. Replace the CTX-370 Trichloro Tablets or CTX-392 Multiaction tablets from the skimmers or doser.
4. Add the correct maintenance dosage of CTX-60 algaecide.

Pay attention to

1. Maintain the correct water level.
2. When renewing water in the pool, analyze the chlorine and pH levels and, if necessary, adjust them.
3. If there is any threat of rain, increase the chlorine and algaecide levels.
4. Check and maintain correct functioning of the chlorine doser.

8. Preparing the pool for winter

When the bathing season is over, continue the maintenance program until the water temperature is below 15ºC. Once this moment has arrived, winterize the pool:

1. Clean the pool well, scrubbing the walls and using a vacuum cleaner.
2. Analyze the pH of the water and make the necessary adjustments to have a pH between 7.2 - 7.4.
3. Carry out shock chlorination with CTX-200/GR Granulated Dichlorine (15 g/m ³ of water).
4. Leave the filter running (8 hours).
5. The next day, add CTX-550 Invernador (5 lt./100 m ³ of water). Leave the filter running for approximately 8 hours to achieve perfect distribution of the product in the water.
6. The next day, clean the filter with CTX-55 Sand Filter Descaler. Don't forget to backwash after cleaning the filter.
7. In the case of cold climates, the water level must be below the skimmers, the pipes and filters must be emptied and a floating object must be placed on the surface of the pool, as a precaution against ice. In temperate climates, the filter should be operated periodically and whenever possible.
8. It is advisable to cover the pool with its own cover. It is important to repeat the addition of CTX-550 Invernador in the middle of the winter season (January/February).

9. Water treatment

To have crystal clear and disinfected water, we recommend the following treatment.

Initial treatment

Carry out shock chlorination with 15 gr/m ³ of CTX-200/GR Granulated Dichlorine or with CTX-250 Rapid Chlorine Tablets (1 or 2 tablets/m ³ ), applying the product directly to the water or through skimmers.

This chlorination must be complemented with an algaecide such as CTX-500/S Concentrated Algaecide with a dosage of 1 lt./100 m3 of water or CTX-60 Algaecide Brightener with a dosage of 2 lt./100 m3 of water.

Maintenance treatment

Chlorine is added to the pool water using CTX-392 Multiaction Tablets or CTX-370 Trichlorine Tablets (1 tablet/20 m ³ of water, weekly). The tablets are periodically placed in the skimmers or in a dispenser.

Approximately once a week, the tablet level should be checked and replaced if necessary. This treatment ensures chlorine residual 24 hours a day. The disinfectant action of chlorine must be supplemented once a week, with the addition of an algaecide such as CTX60 Algaecide Rinser at a dosage of 0.50 lt./100m ³ of water or CTX-500/S Algaecide Concentrate , dosing the product directly into the water, at a dosage of 0.25 lt./100m ³ of water.

Precautions when using chemicals

When using chemical products, READ THE LABEL CAREFULLY and follow the instructions.

Do not mix products together. Add first one product to the pool water and then the other to avoid possible reactions between them.

When diluting a product. NEVER add water; always add the product to the water.

Keep the packaging closed, in a dry place, protected from heat and out of the reach of children.

In case of contact with eyes, rinse immediately with plenty of water and seek medical help.

Avoid contact between pool products and other types of chemicals.
