Granular Calcium Hypochlorite (Shock) - 12-Pack of 1 Pound Bags

This 12-pack of 1lb bags (12 pounds total) of calcium hypochlorite (pool shock) is bagged individually for easy measurement and use. The 65% Cal Hypo Granules work in in-ground, above-ground pools, spas, and hot tubs, making it great for regular maintenance.

The fast-acting calcium hypochlorite and professional-grade formula tackle algae blooms, restore water clarity, and raise chlorine levels to eliminate unwanted contaminants. This professional formula is trusted by pool maintenance experts and solves 90% of pool water problems.

To use, ensure the pool filter is running. Measure 1lb per 10,000 gallons of water and pour it directly into the water, distributing it evenly. Use a pool brush to ensure the granules dissolve into the water and aren't sitting on the bottom. Ensure proper circulation and avoid swimming until the chlorine returns to 1-4 ppm.

The non-stabilized formula (no CYAs) prevents chlorine lock and is effective for all swimming pool types, including pools with liners, gunite pools, and saltwater pool systems. Regular testing of pool water and maintenance are essential for optimal shock treatment results.

It's important to keep this product out of reach of children and avoid direct contact with skin and eyes. Use it in a well-ventilated area and store it in a cool, dry place, away from sunlight. Follow the guidelines and usage instructions provided by the manufacturer, and do not add it directly into the pool floater or skimmers.
