Denitrification (low oxygen) reduces nitrates.

Thanks Wayne, can you explain Denitrification for me? Does this mean
adding macro algea?
The end result is I would like to reduce my nitrates. I keep them under
15pmm via 1/3 water changes each month. I was hoping there was a way I
could do even less and get the same results
