Very nice. You should add starboard to the bottom and silicone it in. Best way to do bare bottom. I would get an apex jr or apex depending on what you want to control. I'm not a big fan of the AI lights. I think Radions are a much better product. That being said I have a 48" rail kit that will allow you to attach the AI to that stand. Let me know if you would like it.

They have the ones l8 2 rise posted at BRK. I picked up a set last week. They are my favorite as they don't have the rust issue especially if you give them a quick rinse in the sink after each use.
DUDE! I love your tank. Different than anything I've ever seen. My only suggestion and this really is being a nit pick, I would love if you cleaned the background so there was more contrast between it and the aquascape/corals. We'll done bro!
Barebottom All the way! I just silicone White Starboard in the bottom now. In the past I just put the rocks on the glass. Either one gets covered in coraline algae and looks awesome!
Couple of my past tanks that were BB.
