Delphin Spa pH Minus

Lowers the pH, granules.

The pH value of the spa should always be between 7.0-7.4. Too low a pH value can attack parts of the bath, such as the pipe system, while too high a pH value can lead to skin and eye irritations. An excessively high pH value can also lead to limescale and metal deposits and make it more difficult to disinfect the spa.
