Measure and check the pH value of the water. If the value exceeds 7.6, take a bucket of chlorine water and add the pH minus. Stir until the powder is completely dissolved and pour the liquid into the skimmer.
Recommended dosage: 5 gr / m2 (5 gr / 1000 L) to lower the pH by 0.1.
Check the pH after 3-11 hours.
Too low a pH can cause the following problems: Corrosion on metals and irritated skin and eyes. An excessively high pH may cause cloudy water and degradation of the disinfectant.
