08-08-2025I used Stability to kickstart the cycle on a new tank and it worked faster than I expected. I dosed it daily for the first week like the bottle says, and by day 5 or 6 ammonia and nitrites were already dropping. I was also using bottled ammonia and keeping things consistent, but I do think this made a big difference. Water stayed clear the whole time and there was no weird smell or cloudiness. I’ve used a few other bacteria starters before and this one seems to actually do something right away. Might not be “instant” like some people say, but it definitely sped things up. I’d use it again for sure.

Technical Specifications
About this item 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 bacteria 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 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.
