Enough plants to absorb nitrate

From my (limited) experience, if you have a lot of plants it wont
necessarily remove nitrates.
Of course there are many variables, but I have 71 community fish in my 72
gallon, heavily planted tank, and Nitrates still measure well under 10ppm. I
have to ADD 0.5 ppm nitrates per day to keep Nitrates in the 5-10 ppm range,
otherwise plant growth slows and Nitrate measures under 5ppm.
Once plants get well established, all forms of Nitrogen are history!
