SeaChem Stability 100 Milliliter

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, Stability contains a synergistic blend of aerobic, anaerobic, and facultative bacteria that help break down waste organics, ammonia, nitrite, and nitrate.

Unlike other products, the bacteria in Stability are non-sulfur fixing and will not produce toxic hydrogen sulfide.

Stability is completely safe for all aquatic organisms and aquatic plants, making overuse harmless.

  1. Katherine Metcalfe –

    I’ve used Stability in my 55-gallon freshwater tank after a recent filter change. The fish showed no signs of stress, and water parameters stabilized within a week. No ammonia spikes, which was a big relief.

  2. Anthony Underwood –

    After switching from a chemical filter to a biological one, I added Stability to help establish the new biofilter. It worked quickly—within 5 days, nitrite levels dropped to zero.

  3. Virginia Avery –

    The product arrived on time and the instructions were clear. I used it in a marine tank with live rock. The system stabilized faster than expected, though it took a bit longer than I hoped.

  4. Caroline Hodges –

    I’ve had multiple tanks over the years and have never seen such consistent results with a biological starter. Stability is reliable and easy to use.
