Stability rapidly and safely establishes the aquarium biofilter, thereby preventing the #1 cause of fish death: "new tank syndrome". Stability 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 overuse.



  • New tank stabilization system for marine and freshwater
  • Rapidly and safely establishes bio-filter
  • Prevents "New Tank Syndrome"


Stability is the culmination of nearly a decade of research and development and represents the current state of the art in natural biological management. 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.


Available in Three Sizes

  • 100 mL
  • 250 mL
  • 500 mL


Directions for Use

Shake well before use. Turn off UV/ozone. Fish and other aquatic species may be introduced at any time as long as dosage is maintained for 7 days. 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. 
  • 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 media such as Seachem Matrix. For emergency ammonia control, use Seachem. Product shelf life is 4 years from date of manufacture.
