Seachem Matrix Carbon

Seachem Matrix Carbon

Seachem Matrix Carbon is a high-efficiency activated carbon filter media for aquarium water filtration, suited to fishkeepers who want to remove organic matter while keeping the effect on pH to a minimum. Its spherical, bituminous coal-based carbon beads are designed for strong water flow and contact with macroporous binding sites.

Key Benefits

• Spherical bead shape promotes optimum hydrodynamics and helps prevent the carbon from packing together.
• High-density macroporous structure targets larger organic molecules, including nitrogenous waste.
• Large surface area and high removal capacity for aquarium organic matter.
• Low ash content means minimal impact on pH; when added to distilled water, it does not raise pH above 7.0.
• Contains the lowest detectable leachable phosphate content among major carbon brands tested.
• Designed to outperform other high-grade carbons in total organic-matter removal capacity, adsorption rate and duration of use.
• Very clean and nearly dust-free formulation.

How to Use

Place Seachem Matrix Carbon where it will receive maximum water flow. It can be used in a canister filter, chemical filtration module or box filter. The bead size allows water to penetrate the media while helping prevent it from escaping through filter bags.

Dosage

250 mL will easily treat 400 L (100 gallons) for several months.

Suitable For

Aquariums requiring activated carbon filtration for the removal of dissolved organic matter. Its macroporous carbon structure is intended for water filtration rather than air filtration.

What's Included

• Seachem Matrix Carbon activated carbon filter media.

Frequently Asked Questions

What does Seachem Matrix Carbon remove from aquarium water?
It is designed to remove organic matter, with macropores that bind larger organic molecules such as nitrogenous waste.

Will this activated carbon affect aquarium pH?
Matrix Carbon has a low ash content and is intended to have very little impact on pH. In distilled water, it does not raise pH above 7.0.

How much Seachem Matrix Carbon should I use?
Use 250 mL to treat up to 400 L (100 gallons) of aquarium water for several months.

Can I use Matrix Carbon in a canister filter?
Yes. It may be used in a canister filter, chemical filtration module or box filter, positioned to maximise water flow through the media.

Does Matrix Carbon release phosphate?
All activated carbons contain phosphate. Matrix Carbon is formulated with low ash content and has the lowest detectable leachable phosphate content among major carbon brands tested.

Why are the beads spherical?
The spherical form supports water movement through the media, prevents packing and provides contact with its macroporous binding sites.
