What is the optimal pH range for pool water?

The optimal pH range for pool water is 7.2 to 7.8. This range is considered ideal because it effectively balances several important factors related to water quality and swimmer comfort.

When the pH is maintained within this range, it helps ensure that the water is neither too acidic nor too alkaline, both of which can cause problems. A pH below 7.2 can lead to increased corrosion of pool equipment and surfaces, as well as irritation to swimmers' eyes and skin. Conversely, a pH above 7.8 can trigger scaling and cloudiness, rendering the water less visually appealing and potentially leading to other maintenance issues.

Maintaining water in the optimal pH range also ensures the effectiveness of chlorine, which is a common sanitizing agent used in pool water. Chlorine works best when the pH is balanced within this optimal range, allowing for better sanitation and water clarity. Consequently, keeping the pH level stable within 7.2 to 7.8 is crucial for both the health of the swimmers and the longevity of the pool facilities.
