What is the ideal pH range for swimming pool water?

The ideal pH range for swimming pool water is between 6.5 and 7.5. This range is essential for maintaining water quality that is safe and comfortable for swimmers. Within this pH range, the effectiveness of chlorine as a disinfectant is maximized, helping to keep the pool water free of harmful microorganisms. Additionally, this pH level helps prevent issues such as eye irritation, skin discomfort, and damage to pool equipment.

A pH that is too low (below 6.5) can lead to corrosive water, which can harm pool surfaces and equipment, while a pH that is too high (above 7.5) can result in scale buildup and decreased effectiveness of chlorine. Therefore, maintaining the pH within the ideal range is critical for the overall maintenance of the pool, for both health safety and the longevity of the pool infrastructure.
