Balanced water is based on 3 parameters: pH, alkalinity (TAC) and hardness (TH). The search for this balance is important because it guarantees the optimal efficiency of chemical products, the preservation of equipment and a perfect bathing quality.
Water balance depends on the use of your pool
The environment and the use of your pool have a direct impact on the quality of the water:
- The environnement ( trees, air pollution,...)
- Number of people using it
- Frequency of swimming
The number of pH, TAC and TH tests should be adapted to the external factors. Your water should be monitored very regularly. once per week - or daily on summer.
Parameters and values of optimal water
Here are some indicators to analyse to understand water quality:
- pH (sanitization) : Ideally, your pool water should have a pH between 7 and 7.4 (for bromine treatment the pH should be between 7.4 and 7.8). These are the optimal values for water disinfection. All about pH
- The TAC (alkalinity) allows to know the concentration of carbonate and bicarbonate ions. This measurement indicates the capacity of the water to absorb pH fluctuations and to stabilize it. The unit of measurement of the TAC rate is the ppm (part per million) or the French degree (°f) is located between 80 and 120 mg/l . By regulating the TAC level of your water (TAC+ or TAC-) you will be able to do what is called "buffering your water." All about alcalinity.
- TH (hardness): TH is the hardness of water, which refers to the concentration of calcium or magnesium ions . It is measured in French degrees (°F) or in ppm.The ideal TH is between 10 and 20°F (100 or 200 mg/l or ppm). The higher the TH, the harder and more calcareous the water becomes. Conversely, the lower it is, the softer the water. All about water hardness.
