The BiOrb Anti-Algae Kit is designed to be used if Algae levels increase to significant levels. If you only have a small amount of algae you are probably over feeding or your aquarium is in to much light.
The Anti-algae Kit destroys the algae making it easier to remove. Standard Filter cartridge should be removed and the Anti-algae filter cartridge installed. 25% of the anti-algae sachet is then added every day for 4 days.
