What’s in the Box 1 x GLB Super Blue Clarifier - 32 oz. Directions Add the required amount of Super Blue Clarifier directly into the water around the edges of the pool and a small amount directly into the skimmer. Run the filter for 8 hours and then vacuum the pool. Use Super Blue Clarifier 4 to 12 hours after each shock treatment, superchlorination, or application of algaecide to remove dead algae or organic debris from the pool water. Use Super Blue weekly or more often depending upon swimmer load. Add 1 fl oz of Super Blue for every 5,000 gallons of swimming pool water weekly. If the pool water is extremely cloudy due to heavy usage, a warm-weather start-up or freshly-added water, you may increase the dose to 1 fl oz for every 2,500 gallons of water. Brand GLB®
