Why is chlorine important in pool maintenance?

Chlorine is essential in pool maintenance primarily because it acts as a disinfectant that kills harmful bacteria and pathogens present in the water. When chlorine is added to pool water, it undergoes a chemical reaction that creates hypochlorous acid, a potent sanitizer that targets and eliminates microorganisms including viruses and bacteria. This disinfection process not only ensures the safety of the water for swimmers but also helps in preventing diseases associated with contaminated water.

While maintaining proper temperature, stabilizing pH levels, and enhancing water clarity are important aspects of pool care, they are not the primary functions of chlorine. Chlorine’s primary role directly influences the health and safety of the pool environment, making it a critical component of effective pool maintenance.
