Can I treat a blue-green algae bloom myself using an algicide such as copper sulfate?
Copper sulfate or other algicides should not be used when toxic forms of blue-green algae are present because it may cause a sudden release of toxins. Contact your county environmental agency or regional Florida Department of Environmental Protection office for evaluation and assistance. How do I get more information about the health effects of blue-green algae? For treatment, advice, or additional information on the health effects of blue-green algae, contact the Aquatic Toxins Hotline at (888) 232-8635 (toll-free), or visit the Florida Department of Health, Division of Environmental Health Web site at www.myfloridaeh.com. What should I do if I see a fish kill? To report fish kills, contact the Florida Fish and Wildlife Research Institute’s Fish Kill Hotline at (800) 636-0511 (toll-free) or on the Web site at Submit a Fish Kill Report.
