I followed the reefkeeping article that is out there if you google aquarium stands.
Here are some pics. Sadly I put water in the tank, no finish work was done just yet!
The dream...
After headers were built, added the 2x6s on 12" center with joist hangers. Nice end result, the bottom of the stand is completely open on this 4'x4' cube
Painted with the red-guard and installed a floor drain underneath
One more shot, lest this turn into a build thread hijack. Hope someone finds some ideas from this...
Well, I am a carpenter, so they are DIY but w/ some experience behind them, but they are all built in my back yard like everyone else, except for this first one I had to build in place.
Still good for ideas and inspiration.
