About this item

Product details

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". 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. 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 over use. Stability® is the culmination of nearly a decade of research and development and represents the current state of the art in natural biological management.

Seems like it helps.

I used this to help cycle my aquariums along with necessary water changes. Granted I changed 50% of the water the first week everyother day due to going from 5 gallons to 10 to 20 gallon tanks for my fish. Bought the fish before the tank kind of deal. But I used this during those changes and for a week once established in there new tank and the cycle was done by the end of the second week. I used the test strips to test the water. At first I stopped useing it then went back to using it when I do water changes. Somehow it makes a difference even though the tanks are cycled and stay below 20ppm nitrates.
