What Is the Difference Between Seachem De*Nitrate and Matrix Bio-Media?

  • We are currently upgrading MFK. thanks! -neo

^how are they optimized for a specific task if they are the same material?

my thinking is that de*nitrate will do a better job of removing ammonia and nitrites than matrix in a canister. because of its smaller size, you could put more of it in the same volume of filter space.

It is in the size of the pores
I couldnt' disagree with you moar

where did you find that information?

how can you disagree with that? it's a matter of fact, not an opinion.

you can fit more de*nitrate than matrix in the same volume because it fills in more gaps.

for example; fill a cup with sand and fill a cup with marbles. the cup with sand has more material, more weight, more surface area.
the only way this isn't true is if the materials are actually different in some way other than size of the granules, and as far as i can tell they're the same material.

Its also a matter of fact that aerobic bacteria that eats ammonia and nitrite is too large to fit inside the sub micron pore structure of de-nitrate therefore matrix will hold more bacteria then de-nitrate for aerobic activity.

i'll ask again; how do you know that the size of the pores are different? can you point me to the source?

it appears to be the same stuff according to what seachem told me in their e-mail and it looks like the same thing:

"Yes, de*nitrate will
do the same thing as Matrix, as far as helping to control
ammonia, nitrites, and nitrates." -seachem
 
Matrix has a outer pore structure of 75 % >25 microns and a inner pore structure of <10 microns. De-nitrate has a outer pore structure of 75% <15 microns and a inner pore structure of < 10 microns. If most of the aerobic bacteria's have a average size of about 18 microns it doesn't take a genius to figure out that Matrix will have a higher aerobic capacity. Seachem explain this quite well on their website. Both products work well for their designed use.

i didn't see any of this^ on their site, can you post a link? and could you cut and paste what you're seeing?

i appreciate that you're trying to help me but i don't appreciate the attitude that i'm getting for asking a question. did i offend you? am i perceiving something that isn't there? :confused:


what i did find is some info that says pretty much what i was thinking:

"de*nitrate&#8482; is also an excellent media for aerobic nitrification and it makes an ideal biological filter in drip trays, canister filters, sumps, or even box filters. "
http://www.seachem.com/Products/product_pages/denitrate.html

"If filter size and capacity are an issue, then de*nitrate&#8482;will provide a more efficient removal of nitrate per volume of product (i.e. you can use less de*nitrate&#8482;by volume than Matrix&#8482;to get the same denitrifying capacity)." (i have to assume that if the structure is equal, you could say the same about it's aerobic nitrification capacity)
http://www.seachem.com/support/FAQs/Matrix.html

"Both de*nitrate&#8482; and Matrix&#8482; are full of macropores that are
ideally dimensioned for the proliferation of nitrifying bacteria. The pore
structure of both de*nitrate&#8482; and Matrix&#8482; permits both aerobic and
anaerobic proliferation. The pores are in the 3&#8211;30 range, ideal for
bacterial entry and proliferation, but too small to permit the entry of

most debris and detritus."
