What is the recommended loading rate of copper sulfate for effective algae control?

The recommended loading rate of 5.4 lbs per acre of surface area for copper sulfate in algae control is based on research and best practices in water treatment. This specific dosage has been found to effectively reduce the growth of algae while minimizing potential phytotoxicity and impacts on non-target organisms in the aquatic environment.

Proper dosing is crucial, as excessive application can lead to harmful effects on water quality and aquatic life, including fish toxicity and disruption of the ecosystem. The 5.4 lbs per acre rate strikes a balance between effectiveness in controlling algal blooms and ecological safety, making it the most suitable choice among the given options for maintaining a healthy balance in treated water bodies.

Understanding the appropriate application rates is key for water treatment operators to manage algae efficiently without causing unintended harm to the aquatic ecosystem.
