The Mineral Sanitizer cleans and softens hot tub water while sitting inside your filter cartridge. You still add dischlor or bromine separately but at a reduced amount. Frog Filter Mate is a disinfectant that contains a patented mineral formula that destroys bacteria while neutralizing acids, which helps keep the pH in an acceptable range with less monitoring. Improves hot tub pleasure by reducing the problems associated with heavy bromine and chlorine useage such as fading bathing suits and premature damage to hot tub equipment or surfaces.
