Initial Dose: When pool has visible algae growth, add 1 quart of Aqua Pure per 20,000 gallons of pool water by distributing around the perimeter of the pool. One half hour (30 minutes) after adding algaecide, add 3 gallons of liquid chlorine per 10,000 gallons of water, or 2 pounds of dry chlorine (calcium hypochlorite), or other equivalent types of chlorine per 10,000 gallons of water. Add Aqua Pure to the water by itself, do not mix or premix with other pool chemicals. Aqua Pure is non corrosive at use dilutions to inanimate surfaces. Discontinue swimming until chlorine residual is 1 ppm. Keep filter system operating continuously for 48 hours after treatment. Backwash filter as required and brush pool daily. Vacuum before and after algae treatment.
Maintenance Dose: Add 4 ounces of Aqua Pure per 20,000 gallons of pool water every two weeks during the swim season. Maintain pH of pool water in the range of 7.2 - 7.6 and maintain correct chlorine residual.
