Copper sulfate in dosages of ________ can control algae blooms.

Copper sulfate is commonly used as an algaecide to control algae blooms in water bodies. The effective dosage for controlling algae blooms typically ranges from 0.1 to 0.5 mg/L. This range is effective because it is sufficient to disrupt the cellular function of algae without causing significant harm to other aquatic organisms or the environment when used correctly.

When copper sulfate is applied within this range, it can effectively inhibit the growth and reproduction of algae, allowing for improved water quality and clarity. Using dosages lower than this range may not effectively control algae populations, while higher dosages could lead to toxicity issues for fish and other aquatic life. Hence, the specified range is crucial for achieving effective algae control while minimizing the risk of negative environmental impacts.
