I just wanted to say a big THANK YOU for your speedy shipment of the order I placed on Monday. I was so shocked to see it on my doorstep on Tuesday!! I don't think we commend one another enough when we do a great job, it's usually only when something goes wrong that you hear about it! So thanks again, and I will be shopping from your store more in the future!

  • High capacity biological filter media
  • Controls ammonia, nitrite, and nitrate
  • Highly porous - enormous surface area (>~700 m2/L)
  • Supports aerobic and anaerobic bacteria species

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.

Matrix™ is completely inert and will not breakdown. It need not be replaced. Since the majority of the bacteria are internal, Matrix™ may be rinsed when needed without damaging the filter. Matrix™ is compatible with all types of wet or wet-dry filters.


  • Great for upgrading your old filter media
  • Easy to clean
  • Can be used in multiple types of filters like canister filter, top filters, sump filters
  • Highly porous media with a large surface area perfect for colonising nitrifying bacteria.

Use 500 mL of Matrix™ for each 200 L of water.


1L of Seachem Matrix without retail packaging. As matrix is very porous, 1L of matrix will weighs less than a 1kg.
