Coptrol is a safe and easy to use algaecide. A powerful alternative to traditional copper sulphates, Coptrol is effective against a wide range of algae including brown slime algae, filamentous green algae, and cyanobacteria (blue-green algae). Coptrol is fast acting, typically killing algae within 72 hours of application.
Water treated with Coptrol is safe for human or animal consumption, and irrigation with no withholding period. It is safe for use around fish, other aquatic animals, plants, wildlife, pets, and livestock.
