Seachem Matrix

Seachem Matrix is a premium biological filtration media designed to provide maximum surface area for beneficial bacteria in freshwater and marine aquariums. Its unique porous structure supports both aerobic and anaerobic bacteria, allowing it to effectively remove ammonia, nitrite, and nitrate from the water.

Unlike many ceramic or stone-based media, Matrix does not break down over time and does not need to be replaced. It works in all types of filters including canister, hang-on-back, sump, and internal filters, making it an ideal choice for long-term, stable filtration.

By promoting a strong, balanced bio-filter, Seachem Matrix helps keep aquarium water clear, healthy, and safe for fish and invertebrates.
