I know people like over-filtration around here, and I don't mind it either, I just don't know how everyone affords it. I was under the assumption when I picked my FX5 up it could easily filter my 220, but based on the results from the last 3 or 4 months I'm starting to believe it can't. My tank currently houses one Jd and one Jag and it is almost always cloudy, any ideas? I do want to admit I have been tweaking the exhaust and am starting to wonder if circulation could be the issue. Right now I have a 3/4 inch plumbing elbow that is shaped like a T connected to the hose. The exhaust is shooting to the two shorter sides of the tank, but it's up in the upper third of the tank and I feel like it's not pushing enough water towards the intake. Also, I do a 20 % water change every week and I have incredibly hard water from my water supply.
