BioGuard SilkGuard Complete Multi-Benefit 3" Chlorination Tablets are a revolutionary product exclusive to BioGuard. These chlorine tablets differ from traditional chlorine because SilkGuard technology softens water by attaching to hard water components and metal surfaces, protecting your pool surface and equipment from scale, corrosion, and staining, while killing bacteria.
