Seachem Matrix 1000ml Biological Filtration Media for Freshwater & Marine Aquariums

Seachem Matrix 1000ml is a high-performance biological filtration media designed to provide superior water quality in both freshwater and marine aquariums. Made from a highly porous inorganic material, Matrix offers massive surface area for beneficial bacteria, enabling efficient biological filtration without the need for frequent replacement.

Unlike traditional bio media, Seachem Matrix supports both nitrifying and denitrifying bacteria, allowing it to remove ammonia, nitrite, and nitrate within the same filter system. Its large 10mm structure ensures excellent water flow while housing bacteria deep within its micropores for long-term stability.

Matrix is completely inert and will not degrade over time. It can be safely rinsed during maintenance without harming beneficial bacteria, making it a long-lasting and low-maintenance solution for serious aquarists. Ideal for canister filters, sumps, and other biological filtration setups.
