About This Item

Keep your pool inviting, clean, and clear. In only 24 hours, HTH® 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 HTH® 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.

1. Test and Balance

Dip an HTH® Multi-purpose 6-Way Test Strip (sold separately) into the water to measure total alkalinity, pH, free available chlorine (FAC), calcium hardness, and cyanuric acid (CYA) or stabilizer. Test the water and adjust alkalinity pH, and other parameters where necessary.

2. Apply Directly to Water

Use a clean, dry scoop; do not use the scoop for other purposes. Add the recommended dosage during evening hours while the filter pump is running. Ensure that the product is broadcast evenly over a wide area in the deepest part of the pool. 

3. Wait and Test Chlorine Level

If granules settle along the bottom of the pool, use a brush to disperse. Once free available chlorine levels are between 1 and 4 ppm, your pool is ready to use again.
