Looks great Mitch! Bet you can't wait to see "stuff" in there..
Like how you've mounted the seaswirls. One nice thing about these larger tanks is the increased elbow room. I thought my 280g was big until I started getting stuff mounted on the light rack. I want an auto feeder up there somewhere but I haven't figured out where I'll be able to shoehorn it in. I don't imagine you're going to run into a lot of the same issues.
