Seachem Stability™ – Safe Start for Aquarium Biofilters
Seachem Stability™ helps rapidly and safely establish the biofilter in both freshwater and marine aquariums, reducing the risk of “new tank syndrome” — the leading cause of fish loss in new setups. Its unique blend of aerobic, anaerobic, and facultative bacteria breaks down ammonia, nitrite, nitrate, and waste organics, helping maintain a balanced and healthy system.
Unlike many competing products, the bacteria in Stability™ are non-sulfur fixing, meaning they will not produce harmful hydrogen sulfide.
