Its unique blend of stable, non-sulfur-fixing bacteria breaks down harmful ammonia, nitrite, and nitrate, preventing new tank syndrome and ensuring a healthy aquatic environment. Safe for all aquatic life and plants, Stability adapts to a wide range of tank conditions, making it a must-have for aquarium enthusiasts seeking reliable water quality management. ## Description From the manufacturer Seachem Stability Water Conditioner 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. The bacteria used in competing products are inherently unstable. The conditions necessary for their growth and development fall into a very narrow range of temperatures, pH, organic loads, etc. When any of these parameters are not strictly within the proper range, the bacterial culture quickly crashes and dies. Stability is not limited this way. The necessary conditions for the growth of Stability's bacteria strains encompass a very broad range. When other bacteria begin to die off (usually from high organic loads caused by the undetected death of an organism), Stability simply becomes more effective.
