Where are you getting your information that matrix has "nowhere near" the space as ceramic rings? Just curious, not trying to be rude or anything. :)

There's just no way it can.... It is a rock with some pores such as lava rock, while ceramic rings are all fully pored and the BB can live on the inside outside and everywhere.

I'm not sure on this, but it would be common sense to assume it has less

Matrix is "fully pored" as well. The pores are not all visible to the naked eye, which allows for many more pores to fit in the same given volume of media.
 
I highly doubt any typical bio media will achieve nitrate reduction. There's a reason people go through so much work creating algae scrubbers and denitrators. You are not going to get nitrate reduction in a typical sump or canister filter.

I have my doubts as well but without conducting an experiment with ot can't say for sure. I have heard many people using this media in canisters and sumps claiming to get nitrate reduction.

matrix is a manufactured product, not a rock. Like I said before I'm pretty sure the porosities are similar.
 
You could test the surface area for yourself. Take equal amounts of Matrix and ceramic rings. Dump them into containers containing the exact same amount of water. Whichever media displaces the most water has the lesser surface area. Simple.

Unless someone can disprove this: http://www.seachem.com/support/SpecificSurface.pdf I will always go with matrix. To the OP; some of your statements are incorrect...the study shouldl clarify it...

I also believe that it will take a few weeks for the nitrate eating BB to fully establish. (I have not read this study in a while...)

It will take anywhere from 3 to 5 months for the nitrate eating BB to fully establish. If you expect nitrate reduction within a few weeks, you will be quite disappointed.
