What is the recommended pH level for swimming pool water?

The recommended pH level for swimming pool water is ideally between 7.0 and 7.4. Maintaining the pH within this range is crucial for several reasons. A pH level of 7.0 is considered neutral, while 7.4 is optimal for swimmer comfort and effective chlorine sanitation. Keeping the pH in this range helps prevent corrosion of pool surfaces and equipment, minimizes skin and eye irritation for swimmers, and ensures that disinfectants work effectively to maintain clear and safe water.

If the pH level is too low, it can lead to acidic conditions, which can cause discomfort for swimmers and damage to pool infrastructure. Conversely, a high pH level can result in the water becoming more alkaline, leading to issues such as decreased effectiveness of chlorine, cloudy water, and the potential for scale buildup on surfaces. Thus, maintaining the recommended pH range is essential for both swimmer safety and the longevity of the pool system.
