Seachem Matrix
Description
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 maintains effective filtration over time without requiring maintenance or replacement.

FAQ
Can Matrix be used in both freshwater and saltwater aquariums?
Matrix is designed for use in freshwater aquariums and is not recommended for saltwater environments due to compatibility and osmotic differences.
Does Matrix require any pre-treatment or conditioning before use?
No pre-treatment is required. Matrix can be added directly to the filter system and will begin supporting beneficial bacteria immediately.
How does Matrix compare to plastic bio-balls in terms of surface area?
Each liter of Matrix provides over 700 m² of surface area, which is equivalent to the surface area of 170 liters of plastic balls. Matrix offers both external and internal surface area, while plastic balls only provide external surface area.
Piers Rees –
I’ve used Matrix in my 55-gallon freshwater tank for over a year. The water quality has remained stable with very low ammonia and nitrate levels. No need to clean or replace it, which saves a lot of time and effort.
Dorothy Turner –
Compared to my previous plastic bio-balls, the filter performance is much better. I noticed nitrate levels dropping steadily, which I hadn’t seen before with other media.
Adam Cameron –
The installation was simple and the media fits well in my filter. I haven’t had any issues with clogging or maintenance. It’s a solid choice for long-term use.
Melanie Peake –
After switching to Matrix, my tank has maintained excellent water chemistry. The bacteria colonization is strong and consistent, and I don’t need to run frequent water changes.
