What is the ideal pH range for swimming pools?

The ideal pH range for swimming pools is 7.2 to 7.6. This range is considered optimal for several reasons. Firstly, maintaining a pH between 7.2 and 7.6 ensures that the water is not too acidic or too alkaline, which can be uncomfortable for swimmers. Water within this pH range is also less likely to cause irritation to the skin and eyes.

Additionally, at this pH level, the effectiveness of chlorine as a disinfectant is maximized, allowing for better sanitation of the water. If the pH level falls below 7.2, the chlorine can become more potent and can lead to skin and eye irritation, while at levels above 7.6, chlorine’s efficacy diminishes, potentially leading to unsanitary conditions.

Keeping the pH within this recommended range also helps in preventing corrosion of pool equipment and surfaces, as well as the formation of scale, making pool maintenance easier and more cost-effective over time. Therefore, the choice of 7.2 to 7.6 is based on health, safety, and system efficiency considerations.
