What is the recommended pH level for spas?

The recommended pH level for spas is crucial for maintaining water quality and ensuring the safety and comfort of bathers. A pH level of 7.4 to 7.6 is ideal because it closely matches the natural pH of human skin and tears, which helps to minimize irritation and discomfort for users. This range also optimizes sanitizer effectiveness, ensuring that disinfectants such as chlorine or bromine can work effectively to keep the water free from harmful microorganisms.

Maintaining the pH within this range helps to prevent corrosion of equipment and surfaces as well, which can result from overly acidic conditions, and minimizes the formation of scale and cloudiness associated with high pH levels. Overall, adhering to the pH range of 7.4 to 7.6 is paramount for providing a safe and enjoyable environment in spa settings.
