£16.66 + VAT (£19.99 inc VAT)

pH Minus is a granular acid for lowering the pH of your pool/spa water if it rises above 7.6. Note: A number of applications may be necessary.

All chlorine based sanitisers become less effective at killing bacteria and viruses as the pH rises ( becomes more alkaline).
Acid/Alkaline conditions are measured on the pH scale which ranges from 0 – 14. Ideal bathing conditions exist at a slightly alkaline level of 7.2 to 7.6 with Total Alkalinity of 80/140 mg/l (ppm).
pH Minus is used to reduce the pH level of your spa/pool water when it goes above 7.6, it can also reduce Total Alkalinity of your spa/pool water.
