Stability® will rapidly and safely establish the aquarium biofilter in freshwater and marine systems, thereby preventing the #1 cause of fish death: new tank syndrome. Stability® is formulated specifically for the aquarium and contains a synergistic blend of aerobic, anaerobic, and facultative bacteria which facilitate the breakdown of waste organics, ammonia, nitrite, and nitrate. The bacteria employed by Stability® are non-sulfur fixing and will not produce toxic hydrogen sulfide. Stability® is completely harmless to all aquatic organisms as well as aquatic plants, thus there is no danger of over use.
