Pure-Spa - Spa pH Plus/Increaser Granules - 1kg & 5kg Options

The ideal spa pH levels are between 7.2-7.6, promoting bather comfort, optimum chemical efficiency and protection of pool and spa plant equipment. Test the pH of your pool or spa water and if it is below 7.2, use pH Increaser to raise it.

1. Pre-dissolve the product in a clean plastic container at a maximum rate of 10g of product per 0.2 gallons (1lt) of clean warm water. Stir well to ensure product is fully dissolved. Carefully add the resulting solution to the spa whilst the pump(s) are turned "on", preferably near to the water inlets to aid distribution.

2. After a minimum of 30 minutes, 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.
