Having the perfect mix of pool chemicals delivers that perfect crystal clear water we dream of on warm, sunny days. Pool chemicals such as chlorine, bromine and algaecide keep the pool water safe to use as well, killing harmful bacteria and other germs that can make a swimmer sick.
Chlorine is the chemical most often used to keep swimming pools and Jacuzzis free of bacteria that can be hazardous to humans.deally, the level of pH in the pool should be between 7 and 8; 7.4 is ideal -- this is the pH of human tears. Once the HOCl and OCl-are done cleaning the pool, they either combine with another chemical, such as ammonia, or are broken down into single atoms. Both of these processes render the chlorine harmless.
