Seachem Matrix 2 L

Seachem Matrix 2 L – Biological Filter Media

Product Overview

Highly porous biological filter media for freshwater and marine aquariums. Matrix provides internal and external surfaces for beneficial bacteria to colonize, supporting ammonia and nitrite processing and helping reduce nitrate once biological activity is established.

Uses

• Establishing and strengthening biological filtration.

• Providing a habitat for aerobic and anaerobic bacteria.

• Supporting the processing of nitrogenous waste and aquarium stability.

• Use in canister filters, sumps, and wet or wet-dry filtration systems.

Key Features

• Highly porous structure offering approximately 700 m² or more of surface area per litre, according to the manufacturer.

• Supports the biological processing of ammonia, nitrite, and nitrate within the same filter.

• Inert material that does not directly affect water pH.

• Does not become exhausted and requires no routine replacement.

• Can be cleaned and reused.

Specifications

• Brand: Seachem.

• Product: Matrix.

• Type: Biological filter media.

• Package size: 2 L.

• Approximate particle size: 10 mm, with natural variations in size and colour.

• Suitable for freshwater and marine aquariums.

Directions for Use

• Use 250 mL per 200 L of aquarium water. A 2 L container treats approximately 1,600 L, based on the manufacturer’s current recommendation.

• Place in the biological filtration compartment where water flows through the media, after mechanical and chemical filtration stages, following your filter’s flow direction.

• A filter bag is unnecessary for most applications, but a suitable media bag may be used for easier handling.

• Use alongside Seachem Stability to help establish biological filtration more quickly.

Recommendations

• Gently rinse in water removed from the aquarium when debris accumulates to help preserve beneficial bacteria.

• Allow time for bacterial colonization. Nitrate reduction varies with aquarium conditions and biological load.

• Continue monitoring water parameters and performing regular water changes.
