Ok, I understand what You said. So, I guess my question is: This occurs because of the specific bacteria that grow in the anaerobic/slightly anaerobic conditions of a Denitrate system, Correct?

They convert it directly from NO3 to N2 gas that then dissipates into the air, Correct?

Whereas, the "Normal" aerobic bacteria in an aquarium convert it from ammonia to nitrites then nitrates, and that's it.

If this is correct, then it explains why I would not expect to find an increase in ammonia and/or nitrites after adding a Denitrafication system. According to Seachem's statements, I would expect both of those to increase while waiting to be processed into N2 gas.

Conformation on my Thoughts/Understanding?
