What is the ideal pH level for swimming pool water?

The ideal pH level for swimming pool water is between 7.2 and 7.8, which is considered optimal for several reasons. First, this range is close to the neutral pH of 7, making it comfortable for swimmers and minimizing irritation to the skin and eyes. Additionally, maintaining the pH in this range helps ensure that chlorine and other sanitizers function effectively; if the pH is too low, the chemicals can become overly aggressive, leading to corrosion of pool equipment, while a high pH can cause reduced sanitation effectiveness and promote the growth of algae.

Furthermore, stabilizing the pH within this ideal range contributes to the longevity of pool materials, helps prevent scale buildup, and improves overall water clarity. Regular testing and adjustments are necessary to maintain this balance for a healthy and pleasant swimming environment.
