Dry Acid (Sodium Bisulphate). Size: 25kg. For use where a decrease in pH is required.
Use 1kg EasyChemicals pH Reducer per 100 cubic metres of pool water (15 ounces per 10,000 gallons). In hard water pools the dose rate can be doubled and in soft water it should be halved.
Ideally the pH of pool water should be maintained around 7.5 and between 7.2 and 7.6 at all times (7.8 in a bromine-treated pool or spa). If the pH rises to 7.6 or above add EasyChemicals pH Reducer into 10 litres of fresh water, using a clean plastic container and mix carefully. Slowly pour the solution into the pool water, close to the return inlets and rinse out container thoroughly after use. After 24 hours re-check the pH and repeat the treatment dose as necessary.
