SilkGuard Complete 3″ Tabs – 3.5 lb.

BioGuard SilkGuard Complete Multi-Benefit 3-Inch Chlorinating Tablets are a revolutionary product exclusive to BioGuard. These chlorine tablets differ from traditional chlorine because the SilkGuard Technology actually softens the water by attaching to hard water components and metal surfaces, which protects your pool surface and equipment from scale, corrosion, and staining, all while killing bacteria. SunShield Technology offers protection from the sunlight while SmartGuard Technology helps the tablets last longer than traditional chlorine tablets. This tablet can be used in a skimmer, feeder, or floater. Last but not least Algae killing crystals help stop algae before it starts.
