Powerful Chlorination: BioGuard SilkGuard Complete 3” Chlorinating Tablets provide effective and long-lasting chlorination for swimming pools. Protect your pool and enjoy clean and clear water with these easy-to-use chlorine-based tabs.
Clearly the best tablets I've found with Algae control. I've had no mustard algae the past 2 years since using this product. Also, they dissolve at a slower pace than normal tablets saving me money. They are never available at my pool store so ebay saves the day.
