I always test both my tank back to back but I always leave the nitrate test out for the second tank and do it about an hour later. Is that long enough?
I've heard shaking the bottle not enough or too much skew the result so that is why I assume we can't do the nitrate test one after another.
Anybody know? It's not in the booklet.
