    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.

      This product is to be used exclusively for the specified purpose in accordance with this description.

      • Check the pH level at least once a week using BAYROL test strips and, if necessary, adjust it to the ideal range of 7.0 to 7.4.
      • To lower the pH-value by 0.1, 100 g of pH-Minus per 10 m³ is required.
      • Dose evenly at several points directly into the water while the circulation pump is running.

      Tip: The pH regulation is the first step to clean pool water and optimal bathing comfort. Check the pH level at least once a week.

      Important notes: To prevent lime precipitation and deposits, the addition of Calcinex® is recommended for hard water.
