These tablets offer the highest concentration of dry chlorine currently available. Designed for slow dissolution, they ensure once-a-week dosing for your pool. Infused with cyanuric acid, they stabilize chlorine against UV degradation, facilitating consistent chlorine levels. This maintains pristine water quality effortlessly. Directions: Add tablets to your feeder or chlorinating device. For floaters or auto chlorinators, use 16 ounces per 10,000 gallons weekly. Note: Some tabs may arrive cracked or broken within the interior packaging due to shipping. This breakage is completely normal and will not reduce the effectiveness of these tablets.
