HTH Pool Care Ultra Chlorine 18.0 Pound(s) Bucket Granular Chlorine

Keep your pool inviting, clean, and clear. In only 24 hours, Ultimate Mineral Brilliance Chlorinating Granules sanitize and clarify, and even soften pool water. The multi-functional 7-in-1 action can also help to prevent stain and scale formation while effectively guarding against bacteria, algae and other organisms. These fast-dissolving granules feature visible blue action to let you know the granules are actively working to produce clear results. To use: Apply directly to pool water. Use only a clean, dry scoop to measure the product; do not use the scoop for any other purpose. Do not use in a floater or feeder. While the filter pump is running, add the recommended dosage of this product during evening hours. When adding this product to your pool, broadcast the product evenly over a wide area in the deepest part of the pool. If any granules settle to the bottom of the pool, use a brush to disperse them to prevent the bleaching of a liner or other damage to the pool surface. Test free available chlorine (FAC) residual with multi-purpose 6-way test strips, sold separately. Do not enter pool until the FAC residual is 1-4 ppm (parts per million). Do not use the pool if the FAC residual is above 4 ppm due to risk of bodily injury.
