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.

Stability contains a synergistic blend of aerobic, anaerobic, and facultative bacteria which facilitate the breakdown of waste organics, ammonia, and nitrate.

DIRECTIONS: Use 1 capful (5 mL) for each 40 L (10 gallons*) on the first day with a new aquarium. Then use 1 capful for each 80 L (20 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 40 L (10 gallons*) once a month or with each water change and whenever introducing new fish or whenever medicating an aquarium.

FAQ from Seachem
Q: What is the temperature tolerance of the bacteria in Stability?

A: The bacteria in Stability in the spore form (basically the preserved bacteria in the bottle) can live through freezing temperatures as long as the water is allowed to thaw naturally without the use of a heating element (if a heating element is used then the more drastic change in temp and pressure will kill the bacteria).
Once Stability is dosed to an aquarium (diluted in an aquarium), the bacteria convert to vegetative state and can handle temp as low as 42 degrees F. Below 42 degrees F the majority of bacteria will die but some will convert back to the spore state which can handle low temp/freezing (see above). Once the water thaws and warms naturally, they will convert back to vegetative and do what they are intended to do.
In the spore form the bacteria can tolerate temps between 180-200 degrees F. In the vegetative state the bacteria can handle temps between 120- 125 degrees F(some have even existed in this state up to 140 degrees F but is uncommon).
