Description Application: The optimal pH range of swimming pool water is between 7.2 – 7.6. Use a pH test kit to determine the pH. Pool Acid pH- is added for adjusting pool water when its pH is above 7.6 (for both Fibreglass and Concrete Pool) while recirculation pump is in operation. Recirculate water for about 3 hours to ensure thorough mixing and check pH. If pH is still above 7.6, repeat the treatment with Pool Acid pH- until ideal pH (7.2 – 7.6) is reached. *Note: Delivery is not available for this product. Please collect at our showroom.
