Easy-Life Bio-Exit Green is a new way to prevent excessive algae growth in the aquarium in a biological way, without chemicals. When used correctly, Easy-Life Bio-Exit Green is not harmful to fish, plants, shrimps and other invertebrates.A biological imbalance can cause plants to grow poorly and leak sugars. These sugars can serve as food sources for unsightly algae (such as beard algae, filamentous algae, brush algae and brown algae).
