Seachem Pond Stability 4L (OasisSeachem) — Commercial Bulk Bio-Filter Blend of Aerobic, Anaerobic, & Facultative Bacteria For Large Outdoor Ponds & Commercial Fish Farms
Seachem Pond Stability 4L “OasisSeachem” (SKU: 724928-2129) is a commercial-grade bacterial inoculant designed to establish and maintain biological filtration in large outdoor ponds, commercial fish farms, and high-volume water features. Containing a specialised blend of aerobic, anaerobic, and facultative bacteria, it rapidly breaks down organic waste, ammonia, nitrite, and nitrate.
Pond Stability’s bacterial strains are non-sulphur-fixing, preventing the formation of toxic hydrogen sulphide gas in dense filter media or pond bottom sediments. This 4-litre jug ensures cost-effective bio-management across massive water volumes.
