Seachem Matrix 500ml / 17oz
Matrix is a high porosity biomedia that provides efficient biofiltration for the removal of nitrogenous waste. Matrix is a porous inorganic solid about 10 mm in diameter. Each liter of Matrix provides as much surface (>~700 m2) as 170 liters of plastic balls! Plastic bio-materials provide only external surface area, whereas Matrix provides both external and internal macroporous surface area. These macropores are ideally sized for the support of nitrifying and denitrifying bacteria. This allows Matrix, unlike other forms of biomedia, to remove nitrate along with ammonia and nitrite, simultaneously and in the same filter.

FAQ
Can Matrix be used in both freshwater and saltwater aquariums?
Yes, Matrix is suitable for both freshwater and saltwater aquariums due to its high surface area and ability to support beneficial bacteria.
How long does it take for bacteria to colonize on Matrix?
Bacteria typically begin to colonize on Matrix within 2 to 4 weeks after installation, especially when used in a properly cycled tank.
Is Matrix compatible with other types of filter media?
Yes, Matrix can be used in combination with other filter media. It is recommended to place it in the middle layer of the filter for optimal performance.

I’ve used Matrix for over six months in my freshwater tank. The water quality has improved noticeably, especially in reducing nitrate levels. It’s much more effective than the plastic media I used before. Easy to clean and maintains good structure even after several washes.
Heather Kerr –
The surface area is impressive. I noticed a drop in ammonia spikes after adding Matrix. It works well with my sponge filter and doesn’t clog easily. A little more expensive than plastic media, but worth it for the performance.

After switching from ceramic rings to Matrix, my tank has maintained stable nitrate levels. The bacteria colonization was faster and the filter runs cleaner. I recommend it for both beginners and experienced aquarists.
