Matrix 500g

Seachem Matrix is a biological filter media for aquarists who want a long-lasting substrate for bacterial colonisation inside their filter. It suits marine, reef and freshwater setups, so the same product can be used across different tanks.

Why it matters

• Each granule measures roughly 10 mm in diameter, which gives the media a physical form that is easy to load into standard filter chambers.
• The total surface area is about 700 m² per litre, equivalent to the surface of 170 litres of plastic bioballs, so a small volume provides a large area for bacteria.
• The material is chemically inert and does not decompose, so it does not need to be replaced on a regular schedule.
• The granules can be rinsed, which allows the media to be maintained in place rather than discarded.

What it works with

Matrix is intended for use in marine, reef and freshwater aquariums and fits filter systems where biological filtration is the priority. Because the granules are rinsed rather than replaced, it is suited to tanks where a stable bacterial population is maintained over time.
