PH Minus 1.5kg
SpaRite PH Minus is a granular product used to lower pH of spa water.
All Chlorine based sanitisers become less effective at killing bacteria and viruses as the pH level rises. Acid/Alkaline conditions are measured on the pH scale which ranges from 0 (very acidic) to 14 (very alkaline). Ideal bathing conditions exist at a slightly alkaline level of 7.2 to 7.6.
SpaRite PH Minus is used to reduce the pH level of your spa water when it rises above 7.6. It can also reduce Total Alkalinity of your spa (please see the Total Alkalinity pages for more information)
Contains Sodium Hydrogen Sulphate. This is a 1.5kg tub.
