Seachem Matrix - 2 Litre Seachem Matrix - 2 Litre is a larger-size high-porosity biological filter media for freshwater and saltwater aquariums, helping support the biofilter for ammonia, nitrite, and nitrate control. Seachem Matrix for Larger Aquarium Filters The 2 Litre size is practical for larger canister filters, sumps, media baskets, and multiple aquarium setups. Matrix provides both internal and external surface area for beneficial bacteria, helping build a stable biological filtration system. Biological Filtration Benefits for Larger Systems High-porosity biomedia for efficient biofiltration. Supports bacteria involved in ammonia, nitrite, and nitrate processing. Each litre provides more than 700 m2 of surface area. Inert media does not break down and does not need routine replacement. Compatible with canister filters, wet/dry filters, sumps, and many media chambers. Can be rinsed as needed without removing most of the internal bacterial population.
