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”
5.0

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...Read More

“Very pleased!”
5.0

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 addin...Read More

“Zero zero zero”
5.0

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 mention...Read More

“Fantastic and then some”
5.0

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+++++

“Nitrate Killa”
4.0

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. (Excep...Read More
