Product Overview

Leisure Time® Renew® Granular is a powerful non-chlorine oxidizer that eliminates organic contaminants such as body oils, cosmetics, and sweat, helping maintain clean and clear spa water. Because it doesn't rely on chlorine to oxidize contaminants, there's no chlorine smell or extended downtime — you can typically re-enter the spa just minutes after treatment once levels normalize, making it a great fit for frequent users. It also enhances sanitizer efficiency, allowing bromine and chlorine systems to work more effectively and last longer, while improving water clarity by breaking down the dulling agents that build up from regular use.

Renew® Granular is compatible with all sanitizing systems, including bromine, chlorine, ozone, and mineral systems, making it a universal maintenance product for nearly any hot tub. The easy-dissolve granular formula mixes in quickly with no residue left behind, and it's equally suited to weekly maintenance or shocking the spa after parties, heavy use, or cloudy water.
