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

That was my thought as well - I'd be interested to hear why 0 nitrates is considered strange.
They'll be going up shortly (as the ammonia cycles to nitrites, then nitrates), but the plants are designed to take a lot of the nitrates out of the water and if you had a low bio-load prior to this, the remaining nitrates should've converted to nitrogen gas and simply 'evaporated' from the tank.
I always had nigh nitrates, but I had a massive bio-load and no plants; only way you can do Cichlids well, IMO.
