Product Details
Trichloro-s-triazinetrione 99.0%
1 to 2 tablets (8 oz each) per 10,000 gallons weekly to maintain 1–3 ppm free chlorine
Compatibility
- DANGER: Never mix directly with calcium hypochlorite, dichlor, or other chemical types

When To Use This
Pro Tip
In high-heat regions like the Sunbelt where chlorine burns off quickly, monitor cyanuric acid monthly to keep it within the 30–50 ppm range; once CYA climbs too high, tablets become less effective due to chlorine lock.
