SANITIZATION
The process of controlling bacteria in the water is known as sanitization. Sanitizaion is not to be confused with the control of algae in the pool water, as algaecides are best used for that purpose. While a wide variety of methods for sanitizing pools are available, the two most common methods are chlorineand bromine. Other processes have also gained more attention, including PHMB (biguanide), ozone and ionizers. Each has its strengths and weaknesses.
