pH-Minus Liquid Domestic works effectively on excessively high pH levels and enables the ideal pH level (between 7.0 - 7.4) to be reached quickly. The formula with 14.9% sulphuric acid has been specifically developed for the care of private pools. 
pH-Minus Liquid Domestic is dosed directly into the pool's circulation system as required and maintains the pH-value in the ideal range of 7.0 to 7.4.
pH-Minus Liquid Domestic 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).
