The correct pH and Alkalinity balance is vital to ensure confortable bathing conditions, maximum efficiency from the sanitiser (Chlorine/Bromine) and to help maintain the fabric of the Swimming Pool, Spa or Hot Tub. The correct pH reading should be 7.4 - 7.6 and Total Alkalinity between 80 - 150 ppm.


  1. Ensure bathers are out of the water when adding chemicals.
  2. Use a good quality test kit to determine the pH and/or the Total Alkalinity reading.
  3. To reduce the pH readings add 50g per 5000 litres of pH &Alkalinity Reducer, sprinkling product directly to the water with circulation on. This application will lower the pH by approximately 0.2.
  4. Only make one addition of pH & Aklalinity Reducer at a time and always re-test the water. Should a further addition be required, please follow step 3 again.
  5. To reduce Total Alkalinity (TA) add 75g per 1000 litres of pH & Alkalinity Reducer with the water circulation on. Add product to the deepest point of the Swimming Pool, Spa or Hot Tub in one application. This application will lower the Total Alkalinity (TA) by approximately 10 - 20 ppm (mg/l).
  6. Always re-test the water after each application.
