Well, my temps are good now, bro. I have a 1-2 degree flux now. My lighting schedule was a bit harsh, too. I had my lights on for too long. I have dumbed it down to about 4 hours with just the MH's, and a couple of hours for the T5's before and after the MH's cycle. My algae growth has started to decline, and my temps are staying lower. The distance from my sump to the tank is around 4.5'. I used nylon hose, and had it cut to spec; that's how I know.
I have a guy coming over tonight to look at my tank and build a canopy for me. It'll be like my last one... a floating style. He's a woodworker by day, and superman by night; so, it should look pretty nice when all is said and done. I just want it to match.

That same guy is going to look at my plans for the next build, too. I'm doing two 350-400 gallon tanks in the den, surrounding the fireplace and TV. A "Texas Den" down here is really the "living room," so I have plenty of space. That build will be with a fishroom.
