Test kit not strips.
I was under the impression that zero nitrates was normal for a planted tank.

When you did a water change, (before the spike), did you replace your filter media or rinse it out in dechlorinated water?
Also, no, the plants need Nitrates. They will eat up Nitrates, yes, but if they bottom out, you will need to apply an additive, (i.e. Seachem Nitrogen), to boost them back up.
