Product Description

Seachem Matrix Bio Media is a highly porous media designed to provide exceptionally efficient biofiltration for single site removal of ammonia, nitrite, and nitrate from freshwater, marine, and reef aquaria.

  • Premium natural bio-filter support media
  • Removes ammonia, nitrite & nitrate from fresh, salt & reef tanks
  • 1 liter is equivalent to over 40 L of typical plastic ball media

Each liter of Matrix provides over 160,000 cm2 (170 sq. ft.) of surface, equivalent to over 40 L (10 gallons) of typical plastic ball media! This product is sold by volume. Cited weight is minimal weight.

Directions: Use 500 mL of Matrix for each 200 L (50 gallons*) of water. Matrix may be placed in any kind of filter, and is particularly effective in a canister filter. Matrix is sufficiently large that no filter bag should be required for most applications. Matrix works well in drip tray systems, but you may find that the larger Pond Matrix is better suited for such applications.

Great stuff MATRIX

Matrix Bio-Media is very good. I now use it in all my filters both HOB and Canisters. Matrix is better than any of the ceramic rings or stars that I have used. Give Matrix Bio-Media a try and you will like it also, a few days and you can see it getting dark, that shows that it is working GREAT

Great Bio-media

Great bio-media, slowly replacing my ceramic, you get a big bang in a small package. Seachem comes through again.

The only Bio Media aquarium hobbyists should be using!

I have 4 tanks up, most overstocked, and though overstocked African cichlid tanks look wonderful, ammonia can creep up along with nitrates, and seriously do some damage on the health of your fish if not careful. With that being said, I have been doing this for 15 years, and though I only use API XP and Fluval FX6 canister filters, that is using what everybody often uses, the ceramic rings, bio chem stars, etc. etc., and knowing that Seachem's Neutral Regulator for new world cichlids and Prime for just about any fresh water fish, one tends to forget about the greatness that is Seachem. So looking at the reviews I decided to try this and already after just a couple of weeks I see a dramatic difference and my PURIGEN has not even arrived yet, still using the Bio Chem Zorb that API makes. Because of this, how you don't have to keep your rings bagged and thrown in a bucket of tank water to keep the bacteria in them, I can freely spray tap water on these wonderful rocks, and still have a great force of biological media that I am now a full believer, that there is nothing better. To all who have not crossed over to the wonderful world of Seachem products for filter media, do so now and leave those ceramic rings and bio chem stars to that of the amateurs, because Seachem has out done themselves again.

Good clean pumice stone

Sure you can purchase garden pumice stone for a cheaper price but if you want a good, clean, ready to use pumice stone media then this is a great product for you.

An Amazingly Efficient Bio-Filter Media

Provides exceptional Bio Filtration in my over stocked/planted 60 aquarium. I use it and ONLY Matrix along with filter floss and the two make an exceptional team in removing toxins and polishing my water to supreme conditions. It is simple, easy, effective and highly efficient as a stand alone longer have any need for any other filter products! I'm Positive you'll love it as well. Washes clean with a quick rinse while NEVER losing any beneficial bacteria...even if rinsed in clorinated tap water as I do bi-weekly.

Wonderful Media

This is an excellent media. The available sizes are a lot for smaller tanks because you use so little. The various sized pieces make it easy to select smaller pieces for smaller filters, or to fill a larger area. Would recommend this product.

I love this stuff...

I love this because I can fit a lot more of this media than the ceramic rings. So far, I've noticed it the last 5 days that my nitrates are going down...

Wei Mei, Chicago IL on 11-17-2012
Good stuff, size, more surface area

I upgraded to another tank and decided to use this matrix media based on other reviews. Too early to tell of the quality, but the size allows me to place more than my previous media into the same size tank, so I assume it has increased the surface area for bio-goodness.

This is the Best Bio-Filteration product On the Market

I've had My 55 Gal. Tank for about three months now, used 20 fish to cycle with, had lots of trouble with ammonia. I've tried everything I could think of, from 50% water changes every other day... I Purchased Matrix and added to my canister filter and with a week ammonia 0 ppm, nitrite 0 ppm, nitrate 0 ppm. the best yet.. My ammonia levels was over 5.0 ppm. it was off the scale.

Will buy again!!

Very fast shipping and great product at a great price...

David, Brunswick OH on 02-29-2012
Will pay more for this than scrubbies

I run two tanks ( overstocked ) and use only seachem matrix. Once cycled neither tank has ever shown even small traces of ammonia or nitrites. Sure the nitrate builds up but the bacteria that grows on this matrix is just awesome. i no longer use carbon or ammonia chips - none of it. Nothing but matrix and filter floss. as long as nothing changes, I will continue to use only seachem matrix in all my cannisters.

Nothing Better

The use of this product has made water changes almost obsolete. The surface area for bio filtration is crazy. I have been using this product for over 5 years. You also never have to replace it, just rinse the muck out and it is ready to go.

Better than the ceramic rings

This works great! Cheaper and better than the ceramic media
