The ideal pool pH levels are between 7.2 - 7.6, promoting bather comfort, optimum chemical efficiency and protection of pool plant equipment. Test the pH of your pool water and if it is above 7.6, use All Swim Pool Acid to lower it.

Application Instructions

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