The recommended pH range for swimming pools is 7.4 to 7.6. This range is ideal because it is close to the natural pH of human skin and eyes, which helps to minimize irritation for swimmers. Maintaining the pH within this range also enhances the effectiveness of chlorine, which is commonly used for disinfection in swimming pools. When the pH is balanced, it prevents the water from becoming too acidic or too alkaline, which can lead to corrosion of pool equipment or scale formation, both of which can compromise water quality and system performance. Additionally, a stable pH level contributes to the overall comfort of swimmers and helps maintain clear and safe water conditions.
