Wow, GREAT looking tank! I really like the aquascaping, black sand, and coral selection... this project has come together really well! I don't know where you got that rock, but it looks really porous and makes for a cool looking aquascape.
Did you look at db366 pics? You may want to before you buy, it isn't as easy as slapping it in there, the hood needs to be heavily modified. Not trying to persuade you one way or another but something to consider.
Very clean mod indeed. So in a nutshell you make the cuttings for the on/off switch, and the fans. Then you attach the fans to the hood from the top of the hood itself?
