EasyLife AlgExit combats green algae in freshwater aquariums, such as beard algae, brush algae and string or thread algae. It is harmless for fish, crustaceans and plants.
Use: Shake before use. Add 10 ml per 100 litres once a week for four weeks. This period may be extended if algae still remain or if spores continue to germinate. For prevention: 5 ml per 100 litres once every two weeks.
A 250ml bottle can go a long way.
