You know, I tried that too on a couple different units I had. I can't remember what the issue was but it wasn't a complete slam dunk either. Upflow does make more sense, for one you can do away with the CO2 recirc line. I wonder if it was I was losing too much CO2 into the tank and I was noticing a depressed pH. Might have been something else. I can't actually remember now.
