Regarding nitrates, I do not add any. My tanks have
never had nitrate readings over 5 ppm, and often hover
near 0 (by means of the somewhat rough AP test). And
yet I am growing vigorous, hungry stemmed plants. The
reason is that my tank is more or less at a nitrogen
equilibrium. Input=output. Without evidence of
deficiency, I see no reason to add nitrates. But
having said that, probably a lot of people in a high
light/co2 tank will experience deficiency.
