SpaChoice 1-Quart Premium Clear and Sparkle Blue Pool Water Clarifier, Pool Clarifier, Made in USA

This is a flocculant designed to coagulate and floc suspended solids from swimming pool water. The solids will be filtered out of the pool or collect on the bottom for removal by the vacuum. Add 1 oz. of Clear Pool Water Clarifier per 5,000 gallons of swimming pool water. Addition should be made once a week to the pool when the filter is running. If the pool water is cloudy due to airborne dust or to high hardness of the water, add 4 oz. of Clear Pool Water Clarifier per 5,000 gallons of water. Allow at least 3 hours for Clear Pool Water Clarifier to work, then vacuum the residue from the bottom of the pool and backwash the filter if necessary.
