Blue Horizons pH minus - Sodium Bisulphate
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). If pool water becomes less alkaline (above 7.6) it also gets more corrosive and less comfortable to swim in.
Blue Horizons pH Minus is used to reduce the pH level of your pool water when it goes above 7.6, it can also reduce Total Alkalinity of your pool water.
