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. Unlike competing products, 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. Stability� is the culmination of nearly a decade of research and development and represents the current state of the art in natural biological management.
