Looks sweet! Can't wait to see what you'll do with the tank.
If I may, one thing I would suggest is to ditch the bioballs. They're soo 1995
plus they will have a tendency to collect a lot of gunk and eventually become a nitrate factory, which you don't want. You shouldn't need the bioballs if you have a healthy collection of live rock in your display tank an possibly some in your sump.
