What is the range for free chlorine in a commercial pool?

The range for free chlorine in a commercial pool is typically established to ensure effective disinfection while maintaining water safety for swimmers. The recommended range of 1-3 ppm (parts per million) strikes a balance that is safe and effective for killing pathogens, preventing the growth of algae, and providing a pleasant swimming experience.

At this level, free chlorine can effectively oxidize contaminants without causing irritation to the skin and eyes of pool users. Too low a level could lead to insufficient sanitation, while levels exceeding this range may cause discomfort and could potentially lead to chemical imbalances in the pool water. For commercial pools, maintaining this optimal range is crucial to ensure both health regulations are met and swimmer comfort is prioritized.
