Seachem Stability

The formula contains a synergistic blend of aerobic, anaerobic, and facultative bacteria that help break down potentially harmful organic waste, as well as ammonia, nitrites, and nitrates.
Seachem Stability uses non-sulfur producing bacteria, meaning they do not generate toxic hydrogen sulfide, and the product is completely safe for all aquatic organisms and plants.
There is no risk of overdosing!

Many competing products use naturally unstable bacteria, whose growth and development depend on a very limited range of temperature, pH, organic load, and other variables.
If any of these parameters fall outside the ideal range, the entire bacterial culture can quickly die, compromising the biological stability of the aquarium and potentially leading to fish deaths.
But Stability does not have this problem: the favorable conditions for its bacterial growth cover a much wider range.
Moreover, when other bacteria start to die (often due to a high organic load related to the death of a fish, plant, or other organism), Stability becomes even more effective at establishing new biofilters.
