Drop Off Reef Tank

[lastlight]

I was thinking the same with the shelf but with that empty void who knows how that affects the overall structure with water pushing down on it? I'd have inner eurobracing everywhere and build the stand edges a bit higher to hide it. So build the rectangle, inner brace it all then construct the shelf by building a hollow box inside and inner brace that. I'm no engineer (I'm a drop-out engineer tho lol) but that sounds do-able.
