Clear and Safe pH Minus is used to lower the pH level of your pool and spa water, it is an essential chemical to keep the water balanced and neutral. Sanitisation products need this to work correctly and keep your family CLEAR & SAFE™ from harmful bacteria and germs.

Water in pools and spas should be tested daily, you are aiming to achieve a pH level reading between 7.2 and 7.6 before adding chlorine. Use pH+ or pH- to adjust if necessary. Pool free chlorine levels should be between 1ppm* and 3ppm* and spas should be between 3ppm* and 5ppm*. Maintain these levels to keep your water CLEAR & SAFE™.
