130 Gal w/no braces on frame!! Ideas???

[tooth517]

I just got a steal on a 130 gal. The guy had pics of it holding water but thats not good enough for me. I want to make 2 supports to prevent excessive bowing. The footprint is 6'x18". Has anyone had to tackle this one before? The guy I got it from machined 2 crossbars out of alum. that I could possibly use in this project. Does anyone have any ideas?
Thanks in advance!!

Glass cross braces would look better and would give it a factory look. Just use the same thickness of glass the tank is made out of.

Aesthetics aren't a priority as I plan to build a canopy, so making it strong without obstructing a canopy is my goal. Glass could work but how would it be secured to the rimstock?
