Product Description


  • 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.



  • Why It's Different

  • The bacteria used in competing products are inherently unstable.
  • The conditions necessary for their growth and development fall into a very narrow range of temperatures, pH, organic loads, etc.
  • When any of these parameters are not strictly within the proper range, the bacterial culture quickly crashes and dies.
  • Stability does not contain any of the aforementioned bacteria.


The bacteria strains in Stability have been in development for over a decade.

The necessary conditions for growth of our bacterial 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 works harder and grows faster! The strains function in fresh or saltwater.

Stability contains both nitrifying and denitrifying bacteria, a blend found in no other product.

Additionally, Stability contains facultative bacterial strains which are able to adapt to either aerobic or anaerobic conditions.

The bacteria in Stability are non-sulfur fixing, another innovation in the industry.

Most other bacterial supplements will form toxic hydrogen sulfide under the proper conditions. Stability will not, ever.


  • 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
