do you see any difference inNO3 with it's use? Or is it combined in existing setups?

Don't have them anymore Brad, and never had algae enough to want to measure. The tanks I mention were 100% fiji premium.

All I know is that is my rock of choice.

Ya, I never went wrong with the fiji. The jakarta I see now looks like it came from someone's garden.

Well, good article but it appears Dr. Ron and Borneman had a simpilar decusion and had the resources to find the answer.

Finally, the interior of the rock has to provide the appropriate physical environment, primarily slow water flow and low oxygen concentrations, to facilitate the appropriate bacterial processes.
Low Oxygen will not create a anaerobic environment. No oxygen does. therefore the anaerobic bacteria will not thrive and Nitrate will not be converted to Nitrogen gas. So is this article about Ammonia -> Nitrite -> Nitrate. Or is it about complete conversion.

I anticipated a reference to the components to the complete nitrogen cycle but never found it.

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

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.
