Sanitizers
Sanitizing water is required to protect swimmers from contact with various waterborne pathogens and organic contaminants. Chlorine is the most common sanitizer and typically the less expensive option. Bromine is an alternative and while a little more expensive, doesn't have the same odor intensity that Chlorine does.
