Need opinions on new tank design

[Starry]

OK, did a little more reading, and came up with this:

(sorry,donno howto make it larger)
My only concern with this lay out is: Wont all the sand end up on the front pane of the glass? Should defiantly stop any detritus buildup. 4more outlets creating a reverse cycle would be awesome, but out of my price range.

Starting to think it would be less $ to get a wave box. But the idea is to keep the tank cluttered from equipment.

Thanks for the tips all.
