Seachem Stability is a high-performance, rapid and safe solution for establishing the aquarium biofilter in both freshwater and marine systems. This product is a unique blend of aerobic, anaerobic, and facultative bacteria that facilitate the breakdown of waste organics, ammonia, nitrite, and nitrate. Unlike competing products, the bacteria employed by Seachem Stability are non-sulfur fixing and will not produce toxic hydrogen sulfide. Seachem Stability is completely harmless to all aquatic organisms as well as aquatic plants, thus there is no danger of overuse. It is the culmination of nearly a decade of research and development and represents the current state of the art in natural biological management. The bacteria used in competing products are inherently unstable, losing effectiveness rapidly when exposed to oxygen and light. Seachem Stability, however, does not contain any of the potentially dangerous and unstable sulfur compounds found in other bacterial additives. Seachem Stability offers unparalleled performance and value to the customer. It is easy to use, with a simple dosing regime of 5 ml per 40 L (10 gallons) on the first day with a new aquarium, and then 5 ml per 80 L (20 gallons) daily for 7 days thereafter. This product is also ideal for routine aquarium maintenance, water changes, setting up new tanks, and after medication treatments. In summary, Seachem Stability is a superior solution for maintaining a healthy, balanced aquarium environment. It offers a safe, natural way to rapidly establish bio-filtration, ensuring the health and longevity of your aquatic pets. With its unique blend of bacteria, it provides a comprehensive solution to waste breakdown and toxin management, making it an essential addition to any aquarium setup.
