Stability is only bacteria to help with decomposing matter, like Stress Zyme Plus. It is not the BB needed to establish a cycle in a tank.
"...StabilityŽ will rapidly and safely establish the aquarium biofilter in freshwater and marine systems, thereby preventing the #1 cause of fish death: "new tank syndrome". StabilityŽ 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.
Unlike competing products, the bacteria employed by StabilityŽ are non-sulfur fixing and will not produce toxic hydrogen sulfide. StabilityŽ is completely harmless to all aquatic organisms as well as aquatic plants, thus there is no danger of over use. StabilityŽ is the culmination of nearly a decade of research and development and represents the current state of the art in natural biological management...."
I used Dr. Tim's and it needs to be refridgerated, that is BB for cycling.
