What is Seachem Stability?

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, facilitating 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 entirely harmless to all aquatic organisms and aquatic plants; thus, there is no danger of overuse.

Benefits of Seachem Stability:

  • New tank stabilization system for marine and freshwater

  • Rapidly and safely establishes bio-filter

  • Prevents "New Tank Syndrome"

  • Controls ammonia, nitrites, and nitrates

  • Removes soluble & insoluble impurities from water

  • Prevents "New Tank Syndrome"

  • No refrigeration is needed

How Does Seachem Stability Work?

The bacteria used in competing products are inherently unstable. The conditions necessary for their growth and development fall into a narrow range of temperatures, pH, organic loads, etc. The bacterial culture quickly crashes and dies when any of these parameters are not strictly within the proper range. Stability® is not limited this way. The necessary conditions for the growth of Stability's™ bacteria strains encompass an extensive 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.



Shake well before use. Turn off UV/ ozone. Use one capful (5 mL) for each 40 L(10 US gallons) on the first day with a new aquarium. Then use one capful for each 80 L (20 US gallons) daily for seven days. Fish and other aquatic species may be introduced as long as the dosage is maintained for seven days. For optimum biofilter performance, use one 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.
