Sanitizers kill bacteria and viruses and keep the water
clean. A low sanitizer level will allow microbes to grow
quickly in the spa water. We recommend using either
chlorine or bromine as your sanitizer.
Spa owners with an ozonator or the Pure Cure system also
need to add sanitizer, although their requirements are
different.
