What is the free chlorine legal range for a regular pool?

The legal range for free chlorine in a regular pool is critical for maintaining water quality and ensuring the safety of swimmers. A range of 1.5 ppm to 10.0 ppm is generally considered too broad and might not provide the ideal balance between effective disinfection and swimmer comfort.

Managing free chlorine levels is essential as they help eliminate harmful pathogens in the water while also preventing issues like algae growth. Typically, the optimal and safe range for free chlorine is around 1.0 ppm to 5.0 ppm for regular pools. Maintaining this level ensures that the chlorine is effective without being excessively strong, which could irritate the skin and eyes of swimmers. Therefore, the best choice would reflect this more balanced and effective range of 1.0 ppm - 5.0 ppm, ensuring maximum hygiene and comfort for users of the pool.
