Building a false bottom

[ejh805]

Hey guys,

So, I had to completely disassemble my pixies tank last night. The bottom cracked length and width-wise.
In stead of going out and buying a completely new tank, could I save about $90 by having some thick, strong plexi-glass cut to the same measurements as the floor and then sealing it in place on top of the existing bottom?
I made a stupid mistake my using a too-small stand for my tank, placing all the pressure on the glass. I'm going to be correcting that as well.

Here are pics showing the cracks. Sorry if they're kinda hard to see.
