Robelle 5-in-1 Swimming Pool Multi-Purpose 3" Chlorinating Tabs contain a proprietary blend of ingredients that will reduce the number of pool chemicals needed to keep your swimming pool clean. Each 3" 8 oz. tab is individually wrapped for easier and safer handling, stabilized to prevent burn-off, and is slow-dissolving to maintain a proper free chlorine level. The built-in clarifier produces crystal-clear water. Stain-inhibitor prevents and removes stains caused by metals and minerals. Includes algae preventer that will leave an algaecide residual to help get rid of algae and prevent it from coming back. Built-in descaler will prevent the build-up of scale which can cause corrosion. Because your sanitizer has these additional chemicals built-in, you will spend less money on pool supplies.
