Chlorine tablets are one of the key chemicals to maintaining your pool water, and 3 inch chlorine tablets are the most popular among long-time pool owners. They are thicker than other pool chlorine tablets, allowing them to dissolve slower and protect your pool water for longer. They are also the ideal size for floaters, skimmers, or automatic feeders and are individually wrapped for your convenience. Tablets contain powerful 90% available stabilized chlorine, 99% Trichlor-S-Triazinetrione. Dosage: approximately 1-2 tabs per 10,000 gallons of water per week.
