SpaChem 5kg PH & Alkalinity Reducer

Product description:

The correct pH and Alkalinity balance is vital to ensure comfortable bathing conditions, maximum efficiency from the sanitiser, and to help maintain the fabric of the spa and hot tub. The correct pH reading should be 7.4 – 7.6 and Total Alkalinity between 80 – 150ppm.


  1. Use a good quality test kit to determine the pH and/or the Total Alkalinity reading.
  2. To reduce pH readings, add 10g per 1000lts of Spa and Hot Tub water by sprinkling the product directly into the water with circulation on. This application will lower the pH by approximately 0.2.
  3. Only make one addition of pH and Alkalinity Reducer at a time and always re-test the water. If a further addition is required, please follow step 1 again.
  4. To reduce Total Alkalinity, add 15g per 1000lts of Spa and Hot Tub water with circulation on. Add the product to the deepest point of the Spa/Hot Tub in one application. This will lower the Total Alkalinity by approximately 10 – 20 ppm (mg/l).
  5. Always re-test the water after each application.


  • Always ensure bathers are out of the water when adding chemicals.
  • Never mix with any other chemicals, including cleaning products, weed killers, and chlorine products, as a dangerous reaction may occur.
  • Always handle products in a well-ventilated area.
  • Always wash hands thoroughly after handling chemicals.
  • Store in a cool, dry, well-ventilated, secure place. Ensure chemicals do not become damp in storage.
  • Instructions and dosages given are a guide to the most effective use.
