The ideal pool pH level is between 7.2 - 7.6, promoting bather comfort, optimal chemical efficiency and protection of pool plant equipment. Rock Water Air's pH Minus is a granular acid for lowering the pH of your pool water if its above 7.6.


  1. Pre-dissolve the product in a clean plastic container at a maximum rate of 100g of product per 2.2 gallons (10lts) of clean warm water.
  2. Stir well to ensure product is fully dissolved.
  3. Carefully add the resulting solution to the pool whilst the pump(s) are turned “on”, preferably near to the water inlets to aid distribution.
  4. After a minimum of 8 hours, recheck the pH level and if necessary repeat the treatment until the ideal pH is established.
