pH Increaser should be used to correct the pH when it is below 7.2. Spa water which is acidic is uncomfortable to bathe in and, if left unchecked, can cause corrosion of metal parts and fittings.
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.
After a minimum of 8 hours, recheck the pH level and if necessary repeat the treatment until the ideal pH is established.
