crazy_eddie -- I hope your still in here. You and I are of the same mold, I think. Toolman Tim has NOTHING on me. If one is good, two is better. I have thought about another poll asking how much filtration is enough and how much is too much. How often should we turn the water over? What rule of thumb should we use -- 2X per hour, 6x, 10,12,20...........?
I also believe that there is no single filtering system that will do the job. A combination of ug filtration w/ power heads added to power filters and canisters are the absolute best way to go. Not only do the particulates get filtered, you increase you bacteria bed a bunch. And that always helps. Going reverse flow on the ugf is a pretty good idea, too, as it increases the O2 to them good bugs.
