Letmeknow, thanks for the constructive advice. I certainly do appreciate it.
There are no board resting on the top of the tank. They are hung from the ceiling, there is a 1/8" gap between the board and the tank, cant see it from the pic.
The left window pane will not be a viewing window. I will probably put a black background up and will not be cleaning it.
I will certainly take your advice on the boards, I had heard that before, but was told to use them because of the concrete floor.
Thanks again, I really do appreciate the comments and advice.
