What is the recommended pH range for pool water?

The recommended pH range for pool water is crucial for ensuring both swimmer safety and the longevity of pool equipment and surfaces. A pH range of 7.2 to 7.8 strikes a balance where the water is neither too acidic nor too alkaline. This range maximizes the effectiveness of chlorine as a disinfectant, reduces skin and eye irritation for swimmers, and helps prevent corrosion of metal fixtures as well as scaling on surfaces.

Maintaining the pH within this specified range also aids in optimizing water clarity and comfort. Water that is too acidic (below 7.2) can cause corrosion of pool equipment, while water that is too alkaline (above 7.8) can lead to cloudiness and scaling, which can diminish water quality and appearance. Thus, the range of 7.2 to 7.8 is widely accepted as the ideal pH for maintaining a safe and pleasant swimming environment.
