A quick question regarding acrylic/repairing a tank

[calvin_orchidL]

Hey everyone,

I have a 10gallon tank which I'm currently using to house a few small aerangis species, and the bottom was accidentally broken during transportation. So now essentially it's a four sided glass tank with no bottom or top. I bought a piece of clear acrylic from HD and planned to cut it to the correct shape and use caulk to seal it in to form a new bottom.

Then I read some of these threads regarding acrylic and warping. I'm just wondering whether this will still happen if I use caulk to seal the edges tight - will this be strong enough to hold it in place, or will it end up putting too much pressure on the glass and leading to more damage?

If that's the case, what other kind of material could I use to repair the bottom? I am on the look-out for professional glass suppliers but I was hoping to be able to pick something up rather than getting something custom made (although now that I'm posting this, I realize I'll need to get some sort of glass cover on top anyway... ). It doesn't have to be clear either. Any suggestions would be appreciated!
