• Multiply the volume in cubic feet by 62.44 to obtain total pounds of water
• 2 ppm is 0.000002 for maintenance
• 4 ppm is 0.000004 for shock reduction

Therefore, to calculate the amount of Copper Sulfate Pentahydrate to treat 1 acre-foot of water (43,560 cu ft) with 2 ppm Copper Sulfate, the calculation would be:

 43,560 * 62.44 = 2,719,886.4 * 0.000002 = 5.44 lbs. Copper Sulfate

Waterscapes & Fountains:

Dissolve 1/4lb CuSO4 in one gallon of water for every 7500 gallons

Swimming Pools:

2lbs (4ppm) per 60,000 gals (8,000 cu ft) to reduce algae, 1lb (2ppm) for maintenance
