in-wall tank people, need help

[christyf5]

ok yet another question!

So I'm currently waffling over the whole recessed/flush mount in the wall. So mounting it flush with the viewing wall would require some bulking up of the wall to hold some of the weight.

I wanted to build the stand to the same dimensions of the tank, yet offset the tank forward to make up for the width of the wall (theres a lip of concrete on the floor that is the width of the wall). So behind the tank the stand would stick out a few inches so I could set stuff on it or possibly stand on it if needed (yay/nay?).

Now because the tank won't be supported completely by the posts at the back (since it will be set forward) do I need to shore up the sides of the stand with extra upright posts?

Is it just miles easier to do a recessed wall tank? I mean after all its only a few inches
