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 Chemistry | Values | Average (Ideal) |
|---|---|---|
| pH | 7.2 - 7.6 | 7.4 |
| Total Alkalinity | 80 - 150 ppm | 120 ppm |
| Calcium Hardness | 150 - 250 ppm | 200 ppm |
| Chlorine (indoor pool) | 0.5 - 1.5 ppm | 1.0 ppm |
| Chlorine (outdoor pool) | 1.0 - 1.5 ppm | min. 1.0 ppm |
| Cyanuric Acid | 0 - 80 ppm | 40 ppm |
| TDS (Total Disolved Solids) | 200 - 3000 ppm | 400 ppm |
| Temperature | 10 - 28 º C |
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.
