InSpire pH Reducer - 1.5kg

Product description :

Ideal pH Range: 7.2 – 7.6
Test the pH of your spa water and if it is above 7.6, use Spa pH Minus to lower it. Spa pH Minus can also be used for lowering Total Alkalinity if it rises above 150mg/l (ppm).


  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 the 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.
