How do you guys feel about these butcher blocks as an aquarium stand top?

I really wanted to do butchers block for a tank... but got the same cautions in the thread above. I also had a friend with a butchers block kitchen island, with an unsupported hang over which... although 2 inches thick, just snapped while I was leaning on it. It would need to be well supported!

I used "butcher's block" for 3 tanks, a 75 g, 10 g, 6 g. All dark walnut, all sealed with pour on top epoxy. This has a catalyst you mix in, and is what's on bartops. Do a thin coat or 2 all the way around, then a 3/16" final thick coat on top and push some over the edges, then smooth them with a brush. This finish can be sanded and buffed to whatever sheen you like, or left glossy if you've gotten it even enough. None of these have moved a fraction of an inch.
The many different strips glued together counteract each others warping energy. Even perfect wide lumber will be sawn into strips, then glued back together, to reduce the tendency to split.
It'll be fine if you seal all 6 edges with something, as others have said.
