## Description

Stability will rapidly and safely establish the aquarium bio filter 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, 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 overuse. Stability is the culmination of nearly a decade of research and development and represents the current state of the art in natural biological management.

Review: Stability: A Biofilter Essential - Seachem Stability is a great product, very simple as it is that great nitrifying bacteria that turns fish waste or food from Ammonia to Nitrites and to Nitrates. Ammonia and Nitrites are severely toxic to fish so establishing a tank with this or seeding it with an already established sponge filter is essential to avoid "new tank syndrome" I have been using Seachem products and stability for months but stability and their prime has been staples for every water change to avoid a cycle crash among my API freshwater liquid master test kit. None of their products mess with water clarity, you will see a slight distortion as they settle into the water collumn, although this disperses rather quickly. I highly recommend.
Review: Easy to Use and Works as Intended - This stabilizer has been simple to use and fits smoothly into regular aquarium maintenance. Dosing is clear, and it integrates well when setting up or maintaining a tank. It’s performed consistently with no issues and does exactly what it’s designed to do. The bottle size is practical and should last through multiple uses. Straightforward, reliable, and effective.

### ⭐⭐⭐⭐⭐ Excellent product
*by J***B on November 11, 2025*

Works great! I was having issues with the nitrite being converted to nitrates because of lack of proper bacteria. I followed the 7 day dosage cycle and this completely turned the tank around. It’s stable and fully cycled now.
