Madmak's 200G Reef Build

[Lampshade]

I love your CL set-up, should work out great. As for the open or in wall set-up, I love the look of my in wall, but it is a pain to access most of the tank. With a 200 it would even be harder to reach the front bottom of the tank. Well worth doing if you plan on having a step ladder close by all the time though, really makes everything look finished and neat, even if behind the wall is a mess of hoses and wires like mine.
