What is the ideal pH range for swimming pools?

The ideal pH range for swimming pools is typically considered to be between 7.2 and 7.6. This range is crucial for several reasons. First, a pH level in this range helps to ensure the effectiveness of chlorine in disinfecting the water and eliminating harmful bacteria. When the pH is too low, chlorine can become more effective in the water, but it may also irritate the skin and eyes of swimmers. Conversely, if the pH is too high, it can lead to ineffective disinfection as chlorine becomes less efficient, and can also cause issues such as scaling on pool surfaces and equipment.

Maintaining a pH level between 7.2 and 7.6 also provides a comfortable swimming environment. Water within this range is less likely to irritate swimmers, which encourages longer and more enjoyable swimming experiences. Keeping the pH balanced within this ideal range is an important aspect of pool maintenance to ensure safe and pleasant conditions for all users.

The other ranges presented do not adequately support the objectives of swimming pool management. For instance, a pH range of 6.0 to 6.5 is too low and can lead to corrosive issues, while a range of 8.0 to 8.
