Seachem Stability 100ml — Compact Biological Starter & Nitrifying Bacteria Liquid Supplement For Biofiltration in Small Aquariums, Fish Bowls & Tanks
Seachem Stability 100ml (SKU: 724947-125) is a compact liquid biological supplement designed to establish biofiltration in small aquariums. It contains a blend of aerobic, anaerobic, and facultative bacteria that process ammonia, nitrite, and organic waste.
Stability helps prevent “New Tank Syndrome” in new setups by building beneficial bio-filter colonies. Its non-sulphur-fixing strains will not generate toxic hydrogen sulphide gas, remaining active across varying pH and temperature conditions.
