BioGuard Brominating Tablets are a totally soluble sanitizing alternative to chlorine. They are designed for use in brominators and because bromine typically dissolves slower than chlorine, this mode of sanitation may require less maintenance. Also, because bromine causes fewer odors than chlorine, it is ideal for indoor pools. These bromine tablets are effective in a wide range of pH levels. This product will provide continuous killing of bacteria and is recommended for pools with recurring algae problems.
