Just wondering what everyones opinion is....

I have a couple 75 gal. tanks that are cracked....one across the bottom and the other down the back. I plan to 'fix' them both. I have fixed a 20 gal. that was cracked along the bottom a few years ago. I bought a piece of plexi glass....cut it to the right size, striped the silicone out of the tank, siliconed the piece over the crack and sealed it up. It hasn't leaked yet. Of course the 75's are larger and was wondering if this would work for them. I plan to fix the one with the back cracked first....by sealing a thick piece of plexi across the whole back then covering the repair with a DIY background....you'd never see the repairs. But with the size of the tank and considering the flexing that glass does from the weight of the water, would this work for a tank of this size?

Plexiglass is a poor choice for repairing a glass tank, as silicone doesn't really stick to it that well, and it has a lot of flexability. The best bet is to replace the broken piece with a new one, although a piece that fits inside will also work, depending on the situation. I would in no way consider plexi to do it, however.
