What is the ideal range of pH for swimming pool water?

The ideal range of pH for swimming pool water is 7.2 to 7.8. This range is crucial for maintaining water that is safe and comfortable for swimmers while also protecting the pool infrastructure and equipment. A pH level within this range helps ensure that chlorine and other disinfectants work effectively to kill bacteria and other pathogens, as their efficacy can diminish outside of this pH range.

Additionally, maintaining pH within this specified range minimizes the risk of skin and eye irritation for swimmers, as water that is too acidic (lower than 7.2) can lead to discomfort, while water that is too alkaline (higher than 7.8) can also cause issues such as scale formation and diminished sanitizer performance. This balance is essential not only for swimmer safety but also for the longevity of pool equipment and surfaces.
