pH-minus lowers the pH of the water. The ideal pH value (indicating the acid/base ratio of the water) is between 7.2 and 7.6.

Instructions for use:

• At the ideal value (7.2-7.6), water care products are most effective while being optimally kind to the skin. Therefore, the pH of the pool water should be checked before using water disinfectants.
• The pH-Minus granules are dissolved in water in a clean plastic container before being added to the pool.
• 10g of pH-Minus /1m3 of water will lower the pH value by approx. 0.1.
• If the pH is too low, it is recommended to use pH-Plus.
