Scalesandfins - Bryan, is that a largemouth your holding in your avatar? It's a damn beast. Nice catch. As far as the Fluval I have been looking at it and I am pretty sure my guess is on point. The intake rests just below the halfway point of my tank, about 14 inches off the bottom and the T shaped exhaust is about 8 inches higher, almost at the top of the tank. I'm thinking the exhaust is circling the top of the tank for the most part leaving the mid to bottom section, which is where the crap hangs out, virtually stagnant. I'm going to try and modify one of those bendable exhausts to fit the output and see if I can switch it up and get a better current that will incorporate more of the tank. By the way another piece of equipment that I am missing is one of the hose holders that go over the tank edge. (The one with the buckles) I have one on the exhaust but not one on the input, and for piece of mind I'd like to pick another up. Does anyone know where to get one cheap?
