Heh... yeah my sand has all kinds of stuff crawling in it. It's been up for over a year by now. Haven't had problems with it. And I'd probably run some kind of remote sand bed even if I take out the sand from the display.
I'm thinking about going bare bottom and upping the flow just a bit. Then I can feed my tank like crazy and get faster growth. I may even take out the Mega-flow and make some sort of Calfo style overflow.
Mainly, I'd like to increase the useable space inside the tank. As big as the 72 bowfront is, it seems like there's hardly any room for the rockscape and corals. There's so many cool corals out there, and it's like I don't even know where to put even a little frag. Not like I have a lot of coral either. Yeah, people have been wondering about all the frags hanging from fishing line in my tank
If I can get more depth, and gain back some space from the center overflow I might be okay for a while. What I should do is get the big Oceanic bowfront

But that won't work either, because I've been lusting after a custom bowfront like the humongo one at Aquarium Concepts, hahaha.. it never ends
Ok, what I should *really* do is stop looking at other people's tanks. After seeing Pat's, Rich's, and New Alameda's bb setups, I keep thinking, "Wow... more room... more corals... MORE CORALS!"
Ugh... this is bad... the more I think about it the more stuff I want to do. Another crazy idea... cut out the center brace and glue in eurobracing along the perimeter of the top frame lip.
Ok, and even crazier idea.... separate all the panels, get wider side panels, make a plywood bottom and put it all back together for a tank with more front to back room...
Sorry for all the thread hijacks.... I have the day off, and no real life, so I'm pretending to have one online
