Sanitizes pool water with long-lasting trichlor tablets that deliver consistent chlorine levels for up to a week. BioGuard SilkGuard tablets combine powerful sanitization with built-in water softening and surface protection technologies.

Key Features

• 91.57% trichloro-s-triazinetrione with algae-killing copper sulfate for complete sanitization
• SilkGuard technology softens water while preventing scale, corrosion, and metal staining
• SunShield and SmartGuard technologies protect chlorine from UV degradation for longer-lasting performance

Use 1–2 tablets per 10,000 gallons in skimmer baskets or automatic feeders. Each tablet dissolves over 3–7 days, making this ideal for weekly maintenance routines.

Maintain pH between 7.2–7.6 for optimal effectiveness. Do not broadcast tablets directly into pool or mix with other chemicals.
