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 use.

pH-Minus is a granular powder of sodium bisulfate that does not cause turbidity. It works effectively with too high pH-values and allows to reach quickly the ideal pH-value (between 7.0 - 7.4).

pH-Minus is compatible with all disinfection methods (chlorine, bromine, active oxygen), and all filter types (sand and glass filters, cartridge filters...) and all pool surfaces (liner, tiles, silico-marbled lining, polyester).

Thanks to the enclosed dosing cup, the dosing of the granules is very easy and the correct pH-value can be precisely adjusted.
