The recommended pH range for Hayward pool water generally falls between 7.4 and 7.6. Maintaining this specific range is important for several reasons. A pH level that is too low can lead to corrosion of pool equipment, surfaces, and potentially irritating water for swimmers, as well as causing chemical imbalances. Conversely, a pH level that is too high can lead to scaling, cloudy water, and reduced effectiveness of chlorine in sanitizing the pool. Regular testing of the pool water, using appropriate testing kits or strips, is essential to ensure that the pH remains within this optimal range. Should adjustments be necessary, Hayward offers a range of chemical products designed for pool maintenance that can help raise or lower the pH as required.
