What is the recommended pH range for swimming pools?

The recommended pH range for swimming pools is between 7.2 and 7.8, which is critical for maintaining water quality and comfort for swimmers. This range helps to ensure that the water is neither too acidic nor too alkaline.

A pH level below 7.2 can make the water too acidic, potentially leading to corrosive effects on pool surfaces, equipment, and causing skin and eye irritation for swimmers. Conversely, a pH above 7.8 may lead to a more alkaline environment, resulting in difficulties in maintaining proper sanitizer levels, cloudiness, and scaling on surfaces. By keeping the pH within the 7.2 to 7.8 range, the water remains balanced, chlorine is more effective, and the overall experience for users is enhanced, making this range the industry standard for swimming pools.
