A granular acidic for lowering the pH of pool water. The ideal pool pH level is between 7.2 - 7.6, promoting bather comfort, optimal chemical efficiency, and protection of pool plant equipment. Test the pH of the pool water and if it is above 7.6, use Blue Horizons pH Minus 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 clean warm 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.
