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. | | | Features: | |
• Supports denitrifying bacteria

 Great Bio BoostNov 02, 2011
By Haz
I read about Seachem Matrix and I thought I would give it a try. Great product and it really helped give my tank the bio boost that it needed to keep Ammonia and Nitrites at 0 ppm.
I have Matrix media in a plastic canister in my extra slot on my Penguin 200, and after about two weeks or so the aquarium settled down and my numbers and levels got in line. I did have to tap some of the big stones with a hammer to make them smaller so they fit just right, but that was fine.

Best Biomedia on the marketOct 06, 2011

I'm using this on my 55 & 125 gallon aquariums. It works great and you never have to replace it. I've heard of people saying it can slow your flow rate, but my canister filters work fine. Great Price on Amazon as always

I like most Seachem products and this is no exception. In my eheim filters it performs beautifully, giving me good water flow and solid bio filtering.

 Half wastedSep 08, 2011
By bdf
The pictures make this look like it is all the same light gray color, fairly small, and all the pieces are about the same size. I have seen postings from Seachem that say the pieces are about 1cm.
What I received in the 1L container was completely different. Less than half of the volume was what I expected. The rest was a lot larger than 1cm, up to 3cm (>2 inches), with a lot of dark gray and even dense rock mixed in. There were several pieces of obsidian which is not porous at all, and many other non-porous rocks mixed in. When I called Seachem tech support they said that was because it was "naturally mined" and the dense rocks like obsidian did not affect the "rest of the product." Nice.
Luckily my application did not require a huge volume so I was able to find just enough without any left over. With so much being unusable Matrix is a very expensive solution. I would not buy it again.
