I like the idea of a cuttlefish/xenia tank with live rock. I'll even give you some xenia if you already don't have some.
Would you consider sumpless? I'm pretty happy with the simplicity of my tank (sumpless, HOB skimmer).
By the way- Chris and Shannon were over here picking up some baby stuff, I showed him my tank and he told me his brother has a great reef tank. We made the connection he was talking about you...
