Pure-Spa pH Minus
£7.29

Pure-Spa - Spa pH Reducer Granules - 1.5kg, 7kg or 25kg

The correct pH balance is vital to ensure comfortable bathing conditions, maximum efficiency from the sanitiser and to help maintain the fabric/components of the spa or hot tub. The correct pH reading should be 7.2 - 7.6 and Total Alkalinity between 80 - 150ppm.

Ideal pH Range: 7.2 7.6 

Test the pH of your spa water and if it is above 7.6, use Pure-Spa Spa pH Minus to lower it.
Spa pH Minus can also be used for lowering Total Alkalinity if it rises above 150mg/l (ppm). 

Application Instructions 
1. Pre-dissolve the product in a clean plastic container at a maximum rate of 10g of product per 0.2 gallons (1ltr) 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. If you are reducing Total Alkalinity, pour the solution in one area in the middle of the spa.

2. After a minimum of 30 minutes, recheck the pH/Total Alkalinity level and if necessary repeat the treatment until the ideal pH/Total Alkalinity is established.
