Hey, are you that guy who wanted to replace half your salt mix with MgCl? If not, I remember someone else using the same lame line about 'going to school for marine biology' to defend their rediculous thesis.
Anyway, here's an excellent two-part article which essentially supports every one of my assertations (fine grain sizes are better for denitrification, denitrification occurs only in anaerobic conditions, sulfate reduction is normal in a DSB, etc.) It also shows that most of your assertations (nitrate reduction occurs primarily in oxygenated areas of the substrate, that coarse substrates support more bacteria, that coarse substrates support more marine life) are wrong. The information about nitrogen reduction is primarily in the second part of the article.

The article provides substantial citations, and I think that, with Mr. Toonen's publication record, you'll agree that he can be considered a greater authority on marine biology, ecology, and common biochemical reactions and pathways than either of us are.
Additionally and interestingly, while I was tracking down this article, I found another article which implies that sulfate-reducing bacteria may actually help facilitate nitrate reduction through the production of iron pyrite, FeS, though this article doesn't deal with a marine environment per se.
Anyway. I showed you mine, now show me yours -- got citations to back up anything that you claim?
