1. Adjust pool water pH to 7.2 - 7.8 range with a total water alkalinity range of 100 to 150 ppm.
2. To control pool water algae, distribute 3 pounds over water surface for each 20,000 gallons of pool water. This will raise pool water chlorine residual to 4 ppm for immediate anti-algae shock treatment and add 1 ppm of chelated copper sulfate for extended algae relief.
3. If algae persists, repeat dosage.
