This may be a dumb question, but this thought just crossed my mind. When testing my tank water should I be testing from the water that comes out of the filter or from the water in the tank? I know the water goes and comes from the same place but I just got to thinking since most of the BB is in the filter maybe I should be testing from that water instead of getting it straight out of the tank?
