How deep to go front to back

[steve fedyk]

The room is 10' wide by 12'-4"deep. I think 8' wide is a nice size, and I don't wont to go over 32" tall. Because its hard to reach the bottom.
At 8' wide I would be able to walk around the back and sides of the pool, ah I mean tank. I can go 36" to 60", quite easly.
The plan is to biuld a steel frame out of 1/4" angle and drop glass in or pylwood with fiberglass. I should be able to put plank on top to lay on to work in the tank. I just have to think light thoughts.
