Does live rock remove nitrates?

No, no O2 is anoxic, low O2 will creat anaerobic. For our purposes, my understanding of the article says this is sufficient within "good rock". Additionally, if you google "denitrification in live rock" you'll get lots of hits to articles that claim"oh ya, lr does do that, although without anything to back it up.

well, not on an exam, but let's use this difference for this discussion...

Interesting article. One thing I take away from it is that the process of "cooking" rock may be a good thing to do every few years.

Sounds good. I'll read up tomorrow and be back

Dr. Rons article although a good read, when it comes to the denitrification it's all based on too many assumptions, how do you create the perfect velocity through live rock? Where do you find rock with a uniform porosity? Way too many things have to happen for this to work.

"it is possible that dissolved materials such as the various chemicals constituting the denitrification cycle do diffuse into and out of live rock; however, it is unlikely that such diffusion moves any significant amount of materials."

Seriously I think the algae growing on your rock is removing more nitrates than your rock along.
For those maintaining zero nitrates without a skimmer, what kind of tests kits are you using?

Actually I believe the difference is anoxic simply means no oxygen as stated but anaerobic means without oxygen and refers more to organisms living without oxygen or replacing oxygen.
