What is the typical range for superchlorination in a pool?

Superchlorination is a process used to dramatically raise the level of chlorine in a swimming pool to eliminate chloramines and other contaminants. The typical range for superchlorination in a pool is indeed between 10-15 parts per million (ppm). This elevated chlorine level helps to ensure that any combined chlorine (chloramines) in the water is effectively broken down, making the water clearer and more sanitary for swimmers.

When superchlorinating, the goal is not only to sanitize the pool but also to bring the total chlorine levels high enough to oxidize any impurities and organic materials present. The specified range of 10-15 ppm is effective for achieving these results without causing excessive irritation to the skin or eyes of bathers, which can occur at higher chlorine concentrations.

This level is significantly higher than regular chlorination levels, which typically range from 1-5 ppm, and this difference is essential for achieving the cleaning effect of superchlorination. While levels above this range can theoretically be used, it is generally unnecessary and may lead to longer wait times for pools to return to safe, usable chlorine levels before swimmers can re-enter.
