Seachem Stability 250ml / 8.5oz
Stability rapidly and safely establishes the aquarium biofilter in both freshwater and marine systems, preventing new tank syndrome—the leading cause of fish death. Formulated specifically for aquarium use, it contains a synergistic blend of aerobic, anaerobic, and facultative bacteria that help break down waste organics, ammonia, nitrite, and nitrate.
The bacteria in Stability are non-sulfur fixing and do not produce toxic hydrogen sulfide. It is completely safe for all aquatic organisms and plants, with no risk of overuse.

I added Stability to my new freshwater tank after setting up the filter. Within a few days, my fish were active and water parameters stabilized. No ammonia spikes, which was a big relief. Easy to use and effective.
Alan Buckland –
My marine tank had high nitrite levels after cycling. I used Stability and noticed a significant improvement in water quality within a week. The fish showed no signs of stress.

It worked well in my 55-gallon tank. The bacteria established quickly, and I didn’t have to wait for a long cycling period. A reliable product for new tank setups.
