Ph Minus 7kg
pH minus reduces the ph level of your spa when it goes above pH7.6. It can also reduce the total alkalinity of your pool if it goes above 150mg/l (ppm). This treatment may be required more than once for the correct pH balance. It is important to maintain a pool with the correct pH level as a high pH level can cause dry skin, cloudy water, lower chlorine effectiveness, scale formation and filter calcification .
