Thanks Ben. I'm using 1" x 4" (which is really Ã‚Â¾ x 3Ã‚Â½) and was debating putting a top on the stand.
With the stand measuring 48Ã‚Â½" wide, I should have Ã¢â€¦â€º" to spare on the inside of each side after the tank sits. Assuming the trim is Ã¢â€¦Â
The last stand that I had mine on was one made by Aqueon and that sat on top of just the perimeter of wood that was only between 1/2 and 5/8 inch. It did seem to bow out after a little while of being on there.
I know my new stand in a bit overkill but it helps me sleep a little better at night and I dont have to worry at all with our little girl running up to it.
I feel that the 3/4" will be plenty wide enough for it to rest on it nicely all the way around.
