For water disinfection to be as effective as possible, the pH value should be between 7.0 and 7.4. To keep pH levels optimal, they need to be measured and adjusted, in private pools 1 to 2 times a week, and in public pools it is recommended to measure 3 times a week. Measurement is carried out using test kits. To lower the pH by 0.1, 0.1 kg of pH Minus is required per 10 m3 of water. Add pH Minus gradually, near the outlet nozzle or evenly at several points in the pool. It is recommended to dissolve the product in a container of water beforehand. Do not add before the filter or before the heat exchanger. Do not mix with other chemicals.
