Leisure Time Renew 5 lbs - 1 Bottle is a
non-chlorine shock treatment. Renew's fast-dissolving granular formula rids spa
water of residual soaps, deodorants, natural oils and organic materials that
can build up in spa water. When Renew is added to the spa water, it reacts with
the bromide and forms a bromine solution to destroy any microorganisms left
behind by the bather. Renew is compatible with chlorine, bromine, ozone and
mineral purifications systems, the Reserve & Renew® System, and is part of the
Reserve & Renew® Chlorine-Free Sanitizing System.
