Seachem Matrix Carbon 2 Liters

Works perfectly, loads easier than messing about with other carbons. You can clean it as well but for the price I just but a new one

A new carbon is in town

Matrix carbon is like no other carbon you've used. It shape is small little balls that pack together very tight without interfering with the flow of water through it. It helps with filtering out the impurities in your water while polishing it at the same time. It can also be used with products such as Purigen to clean your water and give it a crystal clear shine.

Decent price if you stack deals

Came in as described. All the research points toward this being the better carbon. I also bought purigen so we will see who wins out.

Excellent Product!

I am a huge fan if Seachem products & it's all because if this product. I've used other carbons in my H.O.T. Magnum canister filter & will NEVER use anything else but MatrixCarbon! The spherical shape of the carbon and how strong each one is, is amazing! The other carbons I've used looked like it was the left overs that fell on the floor and would disintegrate just by squeezing it between my fingers. MatrixCarbon does not compact like other carbons either & that is why I will never use anything else!

Good stuff

This is a low dust spherical carbon that works great in reactors.Compared to other carbons I've tried, I can get a higher flow through the reactor without tumbling (tumbling carbon is bad, it breaks off fragments that can harm your fish) and it rinses clear much faster.This pairs up well with Phosguard, which is much easier to deal with than GFO for similar reasons.

Great product for the cost

I added this to a reactor after I dosed chemiclean in my 125g reef tank to remove the excess chemiclean in the water system after a 40g water change. It not only took out all the chemical but it also cleared up the water a lot more and made my corals open up more. The reactors flow is only enough to move the top layer and not have it bouncing around all over the place. You do need a sponge or screen in your reactor since its small spheres unlike traditional carbon. I used different carbon before which took longer to take out chemiclean before then matrix did.

No difference in nitrate levels

Nitrate levels stayed at a constant high level, according to the company representative this product will bring nitrate levels down in a salt water fish tank. There was no difference. I would not recommend this product. Spend the extra money and purchase a protein skimmer, use in conjunction of your charcoal/whisper filter for results!

Seachem always a quality product.

Got this at a wonderfull price. As good or better than any other carbon I've used. My first thought was ...its just pelletized carbon in another shape. Nope... it works much better in a smaller amount. I spread about 100-150 ml (about a tenth or 10% of my 1L bottle in a bag) across the tray in my canister filter (cascade 700 in this case) to get the same results I got from the bigger bag of pellets

The Best Activated Carbon!

I've been using in my Cascade 700 for about 2 years, in my turtle aquarium with 35 gallons of water, for my So. Painted Turtle. With this particular activated carbon, I can go a full 2 months before replacing. I account for 40 gallons of water for measuring the amount of Matrix Carbon or 1/2 a cup. My Aquarium water is always crystal clear w 1/2 water changes and artificial plants, every 2 weeks. I feed my 3+" Painted, 2-1/2 yr old, in a separate clear plastic container. I had read that the Seachem Matrix Carbon had the highest rating amongst a couple qualified professional keepers. I did go three months w/o changing, but feel more comfortable doing every 2 months.
