Bacteria thrive in hot water. To keep spa water protected all the time, a residual sanitizer is needed. Simply add SpaGuard's Chlorinating Concentrate to spa water while the pump is running, and they dissolve completely to start disinfecting your spa. Chlorinating Concentrate is also pH neutral to ensure no effect on your chemically balanced spa water. This concentrate can be used in regular doses as a sanitizer, and in shock doses as an oxidizer.
