Key Features

• Fast-Dissolving Granules: Calcium-free formula dissolves quickly and avoids leaving a chalky residue, helping the pool water stay crystal clear.
• Easy Dosage: Simple guideline of 1 lb per 10,000 gallons makes routine dosing straightforward for most backyard pools.
• High Purity Ingredients: Made with 99.5% sodium dichloro-s-triazinetrione and 56% available stabilized chlorine for consistent, reliable chlorine delivery.
• Multiple Packaging Options: Available in several bucket sizes so buyers can choose a 10 lb, 25 lb, 50 lb, or two-pack 50 lb option to match storage and usage needs.

Who It's For

This product suits homeowners with in-ground or above-ground pools who prefer a single granular chlorine that can cover routine sanitizing and periodic shocking. It is a good fit for users who want clear water without added calcium and who appreciate an easy dosing guideline.
