Reinforcing a Sump

[swedeboy78]

Hi Guys,

So I have a 4x2x2 (120 gallon) sump for my 600 that was built with what looks like 1/4" acrylic. This is freaking me out a little, especially when full. Do you guys know of a simple, innovative way to reinforce it so it won't blow out on me?

Here is what it basically looks like: http://www.sealifesystems.com/images/P/ap400 copy1.JPG

Build a frame around it, like a roll cage.
Glue interior and exterior bracing made from equal thickness acrylic from front to back
