What is the ideal range for pH in a public pool?

The ideal range for pH in a public pool is typically between 7.2 to 7.8. This range is crucial for several reasons. First, it helps ensure that the water is safe and comfortable for swimmers. A pH level within this range minimizes skin and eye irritation, which can occur if the water is too acidic or too alkaline. Additionally, maintaining the pH in this range allows chlorine, or other disinfectants used in the pool, to be more effective at killing harmful bacteria and maintaining water clarity.

Furthermore, pH levels outside of this optimal range can lead to various maintenance issues for the pool. For example, low pH (acidic) can lead to corrosion of pool equipment and surfaces, while high pH (alkaline) can cause scaling and cloudiness in the water. Keeping the pH levels stable within 7.2 to 7.8 helps in the overall management and operation of public swimming facilities, ensuring a pleasant experience for users and reducing long-term maintenance costs.
