Therefore, it makes sense what when copper algaecides are being considered that you want to ensure that a solution is used that contains the smallest possible amounts of copper that can still produce the best results. Physically remove lake weeds & muck where snail gather. The toxicity of copper varies with Total Alkalinity (the concentration of calcium carbonate equivalents).

He has studied Swimmers’ Itch for 50 years and is now retired, but his website states: For more than 50 years, the application of copper sulfate as a molluscicide was used on some of the larger recreational lakes to break the life cycle by killing the snail intermediate hosts. To get to 0.4 ppm copper ions in a 10,000 gallon pool, you would need (0.4 mg Cu/liter) * (10000 gallons) * (3.7854 liters / gallon) * (249.7 mg CuSO 4 â€¢5H 2 O) / (63.546 mg Cu) * (1 ounce / 28350 mg) = 2.1 ounces weight of copper sulfate pentahydrate.
