What is considered the ideal pH range for swimming pools?

The ideal pH range for swimming pools is essential for maintaining water quality and ensuring the comfort and safety of swimmers. A pH level between 7.4 and 7.6 is recommended because it is close to the natural pH level of human tear fluid, which minimizes irritation to the eyes and skin and maximizes comfort for swimmers.

Maintaining the pH within this range also enhances the effectiveness of chlorine as a disinfectant. Chlorine performs best in this slightly alkaline environment, helping to ensure that the pool water remains sanitized and free from harmful pathogens. Additionally, a balanced pH helps prevent scaling and corrosion of pool equipment, which can lead to costly maintenance issues.

While some of the other options suggest acceptable ranges, they either fall outside the ideal zone or extend it too far, potentially leading to issues with swimmer comfort and water chemistry.
