Seachem Matrix is a highly porous filter medium that ensures the efficient removal of nitrogenous waste products.

The diameter of a single grain is about 10 mm, and the total surface area in one liter is over 700 m2, which corresponds to 170 liters of plastic bio balls.

Due to its structure, Seachem Matrix enables the settlement of microorganisms both in the shallower and deeper part of the pores. Additionally, they are of optimal size for nitrifying and denitrifying bacteria. This makes it possible to get rid of nitrates, nitrites, and ammonia at the same time.

Matrix is chemically inert and does not break down. It does not need to be replaced. Since most bacteria inhabit the pores, the granules can be washed if necessary. Matrix is suitable for use with all types of filters.

Seachem Matrix is available in 500ml,1l, and 2l bottles.
