Chlorine-based pool water systems have been around for decades. These are some of the best pool water sanitization options you can go for.

If your pool water system is chlorine-based, then the major disadvantage that you’ll need to deal with is that such a pool is high maintenance. As an element, chlorine is considered unpredictable. There are times when chlorine ends up reacting too well with various things.
