pH-minus granules lower the pH value of the water and are dosed directly into the water if the pH value is too high (above 7.4). Always read the label and product information before using. pH-Minus is a granular sodium bisulfate powder that does not cause haze. It works effectively with very high pH values ??and allows you to quickly reach the ideal pH value (between 7.0 - 7.4). pH-Minus is compatible with all disinfection methods (chlorine, bromine, active oxygen), and all types of filters (sand and glass filters, cartridge filters...) and all pool surfaces (liner, tiles, silico-marbled lining, polyester). Thanks to the closed measuring cup, dosing the granules is very easy and the correct pH value can be adjusted precisely.
