Well, I am a little surprised that someone remembered my claiming this. Still, honesty and that slight possibility seemed to demand that I come clean.

I have a very hard time with this if it's over 20 ppm. That's one of the things I like about using the strips.
Speaking of strips ...

What are the gradations on the strips? Does it go from 0 ppm to 20 ppm? Or, does it have readings in between? Also, is it possible that you lowered your nitrate levels through water changes?
