TANK STABILIZATION: Seachem 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”.
TREATMENT: 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.
BACTERIA GROWTH: The necessary conditions for the growth of Stability’s bacterial strains encompass a very broad range. When other bacteria begin to die off (usually from high organic loads caused by the unknown death of an organism), Stability simply becomes more effective.
USE: Shake Seachem Stability well before use and turn off UV/ozone filter. 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 the dosage is maintained for 7 days.
SAFE: 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.

Working perfectly!
First time setting up an aquarium here. I wanted to get some tetras soon but I hear they prefer a well established tank and Stability is working perfectly to make that happen. Water was a little cloudy but is clearing up and my levels are beginning to stabilize nicely with only three days of use.

Gotta have it
I’ve been using this product for over a decade and I’ll never stop using it.Great way to to prevent a mini-cycle a.k.a. new tank syndrome after doing a water change and cleaning your filter.Also great to reduce the cycling process to a new setup.All and all Stability is a must have for anyone in the aquarium hobby

Great when adding livestock mid-cycle or when toxins spike and you need to act (best used with prime for this).This small bottle lasts me ages so worth the price but may last less long if cleaning filter a lot
