About the right water balance

Your pool’s water balance can be affected all year round due to endless contact with substances like debris, wind, rain, swimmers and animals entering the water. To maintain proper water balance, you will need to look at the temperature, pH value, alkalinity, calcium hardness, chlorine, cyanuric acid and (TDS) Total Dissolved Solids. It is recommended to keep them in the right value indications and these are:

Water balance value indicators

Pool Water ChemistryValuesAverage (Ideal)
pH7.2 - 7.67.4
Total Alkalinity80 - 150 ppm120 ppm
Calcium Hardness150 - 250 ppm200 ppm
Chlorine (indoor pool)0.5 - 1.5 ppm1.0 ppm
Chlorine (outdoor pool)1.0 - 1.5 ppmmin. 1.0 ppm
Cyanuric Acid0 - 80 ppm40 ppm
TDS (Total Disolved Solids)200 - 3000 ppm400 ppm

Parts per million (ppm):

Measurement used to specify the parts of a substance, such as chlorine, by weight in relation to one million parts by volume of pool water. Ppm can also be written as mg/l and g/m3.

Essenstials in swimming pool water treatment:

There are 3 main objectives to be reached.

1. Bring the water into balance, meaning avoiding corrosion of metal parts and grout (joints) or scale deposit and staining.

2. Make sure the water is safe. The water should be free from pathogenic microorganisms (bacteria and viruses). Rule: water should be disinfected and disinfecting.

3. Make sure the water is clear. Maintaining clear water without turbidity, which reduces the demand of disinfectant and is more attractive.
