Easy-Life Algexit 500ml

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.
