1.)My inwall tank bottom sits at 39". Perfect height for standing and viewing. If you plan seating mostly go for about 35"

2.) my cut out for the sides put the whatever the side panes were behind the wall. That way I din't have to see it. The top is probably about 1/4-1/2 below where water line is. Remeber it will actually be a bit above the overflow point. And the more sump turnover the higher it will be! You don't want a gap, else light will shine out and not to appealing or clean looking

3.) foam will compress very very little. say your tank is 500g. That is ~4000# filled plus say tank weighs 600# Your at 4600# You have a bootom surface area of 96x34(3264 sq in) So you are at about 1.41 Pound per Square In. Not a lot!



Looks lik eyour tank is 34" front to back. You are going to want front access. Mine is 36" and I would never be able to reach the front from the back,
