What is the recommended range for pH levels in pool water?

The recommended range for pH levels in pool water is primarily set to ensure optimal sanitation, comfort for swimmers, and the longevity of pool equipment. A pH range of 7.2 to 7.8 is ideal because it maintains a balance where chlorine is most effective at sanitizing the water. This range also minimizes skin and eye irritation for swimmers while ensuring that the water remains clear and inviting. Staying within this pH range helps to avoid issues such as scaling or corrosion of pool surfaces and equipment, which can occur if the pH is too high or too low.

Maintaining pH between 7.2 and 7.8 ensures that the water is safe and pleasurable for users, aligning with best practices in pool management. This range is considered slightly basic, which is optimal for swimming pools to function efficiently.
