What are the solutions to blue-green algae?

The most effective solutions for controlling blue-green algae include reducing nutrient levels in the water, improving water circulation, and maintaining healthy aquatic plants. Reducing nutrient levels can be achieved by limiting the amount of fertilizer and other nutrients that enter the water and by improving sewage treatment. Improving water circulation can be accomplished with aeration and by increasing the flow of water. Finally, maintaining healthy aquatic plants helps to keep the algae from overgrowing and provides natural filtration.
