OK without rim (24 x 18 x 16)?

Ok, I definitely can't get between any of the seams with a razor or fishing line - the panes are literally right up against each other.

Could I use acetone to dissolve or soften the bond in each corner?

Bought acetone, and started at the bottom corner of one of the seams to get the razor in - it worked!!

Took 40 minutes, but I got the tank apart with minimal damage to the edges of the panes.

Thanks for the tip that the gap is bigger in the bottom!
