What should the ideal pH range be for pool water?

The ideal pH range for pool water is 7.2 to 7.8. This range is considered optimal for several important reasons. Firstly, maintaining the pH within this range ensures that chlorine, the most common sanitizer used in pools, is effective at killing bacteria and other pathogens. At a pH of 7.2 to 7.8, chlorine works best to provide sanitation while minimizing irritation to swimmers' eyes and skin.

Additionally, this pH range helps prevent scale formation and corrosion in pool equipment and surfaces. If the pH is too low, the water can become acidic, leading to potential damage to pool infrastructure and discomfort for users. Conversely, if the pH is too high, it may cause cloudiness in the water and decrease the effectiveness of chlorine, potentially leading to water quality issues.

Overall, keeping the pH within 7.2 to 7.8 promotes a safe and pleasant swimming environment and contributes to the overall health of the pool system.
