BioGuard SilkGuard Sticks contain a metal stain inhibitor, scale preventer and water softening agents. This sanitizer will last longer compared to chlorine products such a liquid bleach or calcium hypochlorite, as it contains sunlight-protected chlorine. It’s the perfect solution for clear, inviting pool water.
How to Use: Apply sticks directly to feeders, floaters or skimmers
Hot weather, heavy pool use and rain may require higher usage rates to maintain proper chlorine residuals
Controls bacteria in swimming pool water
Pro Tip: To make your chlorine last longer try our BioGuard Silk Smart Sticks, that have a SmartGuard coating that releases chlorine at a slower rate than Silk Sticks.
