Seachem Matrix is a biological filter material with a high porosity for the removal of nitrogenous waste. Matrix is a porous, inorganic and hard grain of about 10mm in diameter. Each liter of Matrix has an area of approximately 700 m 2 . Where plastic filter material only offers an adhesion surface on the outside, Seachem Matrix has both an external and internal macro-porous surface. This macro-porous surface is ideal for housing nitrifying and de-nitrifying bacteria. This enables Matrix, unlike other filter media, to remove nitrate along with ammonia and nitrite in one and the same filter.
Seachem Matrix is completely inert and will not perish. Replacement is not necessary. Because the bacteria are mostly internal, Matrix can be rinsed out without causing damage to the filter operation. Seachem Matrix is preferably used in a canister filter, but is also suitable for use in all other types of wet and dry filters.
Available in 1L
Use 250ml Matrix for every 200 L of water. Matrix can be placed in any type of filter and is particularly suitable for use in an external canister filter. Matrix is large enough to be used in filter baskets without a filter net. Matrix also works great in trickle filter systems. Tip: combine with Stability to quickly create a well-functioning bio-filter.
