What is a common method for managing chloramines in pool water?

Shock treatment with chlorine is a common method for managing chloramines in pool water because chloramines are byproducts formed when chlorine reacts with organic contaminants such as sweat, urine, and other substances. When chloramines are present, they can give off unpleasant odors, irritate the eyes and skin, and cause a decrease in water quality.

Shocking the pool involves adding a higher dose of chlorine than the normal maintenance level, which helps to break down the chloramines and convert them back into free chlorine. This process not only eliminates the chloramines but also ensures that there is sufficient free chlorine available in the water to continue providing disinfection.

The other methods listed do not effectively address the issue of chloramines. Reducing filter time may decrease the overall filtration and circulation of the pool, resulting in a buildup of contaminants. Adding more stabilizer does not directly impact chloramine levels and may even lead to more problems if not managed properly. Lowering the water level might temporarily dilute the concentration of chloramines but does not actually eliminate them from the water.
