Seachem

SeaChem 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 (<162 m) as 40 liters of plastic balls! Plastic bio-materials provide only external surface area, whereas Matrix provides 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. Use 1-2 Liters of Matrix for each 100 gallons. 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. Marine or freshwater use.

Unbelievable

2 liters of Seachem Matrix fit perfectly in one of the baskets in my large Marineland canister filter. After researching the very best filter media for my canister, I added Seachem Matrix with a poly filter, RowaPhos, 2 Chemi Pure blue and a fine filter pad. This combo has made my already clear reef even clearer...unbelievable!

Very pleased!

II I am very pleased with the quality of this product! I was resigned to the long drudgery of waiting six weeks or so for my new reef to cycle. After only a few days with Matrix, the other wise skyrocketing nitrate not only leveled it dropped from approx. 10ppm to .25ppm in three days after adding Matrix. Good stuff!

Sulphur Denitrator use

Works great in my sulphur denitrator. Went from over 150 ppm to 0 within weeks.

Zero zero zero

I run this in a few mesh bags in my 30 gallon sump between bubble baffles. This is way easier than bio pellets, dosing etc. my 120 marine tank has no nitrate, no nitrate and I reduced the amount of gfo I was using. This is one of the best things I did for my tank and I do as another poster mentioned by just rinsing one Of the bags every other month In clean saltwater. It is also very useful when you need to get a quarantine tank running right away by using a little from one of the bags in my sump to my power filter.

Fantastic and then some

Learned way back at the fantastic offerings of Seachem. This is a highly porus almost volcanic looking rock and as long as you keep large pollution out of it will last for years. Huge surface area that rivals all the others and mega cost effective versus results. A+++++

matrix vs bio pellets

it takes the same amount of time to culture as bio pellets I'm finding similar results.

The Best

This is the best high-flow biomedia I have used to date. I use Seachem's Pond Matrix in wet-dry filters and this in canisters. The results have been a very stable and healthy biofilter every time. I'm not completely convinced of it's ability to house denitrifying bacteria under the higher flow rates (>100gph) it is usually paired with. It's my guess that de-Nitrate combined with flow rates ~30gph is a better approach to cultivating the anaerobic bacteria that can help eliminate nitrates.

Nitrate Killa

I use 6L of this in my sump. I have a 180 gallon tank, moderately stocked, heavily fed. I just put it in several large mesh baggies, give it a good rinse and drop it in. Once a month I pull out half of the bags and give em a good rinse in clean saltwater. My nitrates are never above 2 mg/L. (Except for that one experiment with npx biolplastics.) After a few weeks of running this, your nitrate issues will dissapear. Seachem solid. I recommend this to everyone who sets up a marine tank, you can actually use less live rock than recommended if you do. Four stars because for calcium carbonate gravel, it seems expensive.
