Seachem Stability – Rapid Biofilter Establishment for Freshwater & Marine Tanks
Stability is a new tank stabilization system designed to rapidly and safely establish a healthy aquarium biofilter, preventing the #1 cause of fish death: New Tank Syndrome. Formulated for both freshwater and marine systems, Stability® contains a synergistic blend of aerobic, anaerobic, and facultative bacteria that break down organic waste, ammonia, nitrite, and nitrate efficiently.
Unlike other bacterial products, Stability®’s strains are robust, non-sulfur fixing, and will not produce toxic hydrogen sulfide. Completely safe for fish, invertebrates, and aquatic plants, Stability® ensures your aquarium is stable and thriving without risk of overuse.
