The "new tank syndrome" is the most common cause of fish death and can be easily prevented by adding Seachem Stability in your new freshwater and marine tank. Seachem Stability quickly and safely establishes the aquarium biofilter in freshwater and marine systems. It stabilises the water condition, allowing bacterial culture to thrive, which in turn helps fishes, corals and plants to adapt quickly in the new aquarium. Stabilise new tank - marine and freshwater. Rapidly establishes bio-filter. Prevents "New Tank Syndrome". Special Formulation 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. Non Toxic 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. Seachem Stability stabilises the water condition, allowing bacterial culture to grow. Directions Shake well before use. Turn off UV/ozone. Use 1 capful (5 mL) for each 40 L (10 US gallons) on the first day with a new aquarium. Then use 1 capful for each 80 L (20 US gallons) daily for 7 days. Fish and other aquatic species may be introduced at any time as long as dosage is maintained for 7 days. For optimum biofilter performance use 1 capful for each 80 L (20 US gallons) once a month or with each water change and whenever introducing new fish or whenever medicating an aquarium. Stability should ideally be used in conjunction with biological filtration such as Seachem Matrix. For emergency ammonia control, use Seachem AmGuard.
