Ford, NO3 readings of 0 have nothing to do with RO/DI systems, but a reading of 0 is deff possible if you have enough plants with a light stocking. Plus, any test kit for anything else other than NO3 (nitrate) is useless.
Zach. A couple of things. Is this a planted tank?
What test kit?
Liquid? If so, are you shaking the second nitrate bottle a while (45s to a minute or two, can not be stressed)
Whats the light schedule??
