My question is can this be used as a permanent biological filtration? I'm thinking of swapping out my ceramic rings for this... Actually want to get the matrix but, seems not too many places carry and if they carry it shipping is a killer! Asking because it says it does Say it gets exhausted but, does this mean only for the "de-nitrate"? Biologically can this be used continueous? Thanks for any help!
Seachem De-nitrate

If it has a rough surface then BB will grow but with a name like that what I am guessing is it either has some chemical to reduce nitrates or it can grow anaerobic bacteria. Are you using it for a reef?
I think being more a chemical like filtration media you should stay away from it.
Matrix is more what your looking for imo, I would use de-nitrate in a reactor in the last section of the sump to do nothing more then remove nitrates. Its the same as purigen pretty much, also very smooth so I doubt you would be getting even 1/8th of the surface area/ volume ratio compared to matrix.

Thanks was looking for a reply like that. I'm looking for matrix but shipping is soo expensive was thinking of other options. Thanks I was just about to order the de-nitrate...
Yeah those ceramic rings are good but looking for something that lighter and that doesn't take as much space so I looked into seachems matrix n de-nitrate. Btw I ordered the matrix and hopefully it'll be in about 4 days.
I have the whole container/ jar in my sump. seems to work good...But Prob better off with the matrix though...
I have never tried matrix. I know it is good though because Seachem made it 
But to me it looks like some rocks.
