Chlorine is a common disinfectant and pool chemical product found in many pools. It consists of hypochlorous acid and hypochlorite ions which break down organic material. Free or available chlorine in the pool kills most bacteria, algae and pathogens. This chemical also reduces fungal overgrowth. However, high free or total chlorine can be unhealthy and lead to itchy skin, red eyes, and other side effects. Therefore, a salt chlorinator is a better option for most pool owners. The VX9T Chlorinator is an automatic sanitation system making it easy to set and maintain.
