    Fritz Algae Clean Out is an algaecide that effectively, rapidly eliminates existing algae growth. It does not prevent new algae growth from occurring. To prevent that, you have to remove any excess nutrients (foods, phosphates, direct sunlight) from your aquarium or pond. Ornamental plants can be used to consume some of those excess nutrients; heterotrophic bacteria such as in our FritzZyme 360 and FritzZyme 460 products.
