I'm sorry to hear about that. My 55 gallon leaked about 10 gallons of water on my floor after I woke up and seen it. Yep..it sux...My leaks were coming from the bottom middle back glass(by the black frame). I basically didnt know what to do or who to call. I guess I did the quick thing..ran to local fish shop and replaced that sucker. Took all the water out in like 8 5-gal buckets and a garbage can and a cooking pot
lots of water on the floor. Trust me my gf wasn't to happy with it but what could I do. That was such a pain to take everything out and do an emergency change. Ohh and the worse part about it was i had to move it later on cuz the gf didint want it there also it was attracting much more alge close to the window so... My other tank I'm just gonna sell it as a reptile tank so both ways I guess I'm ok. Sorry I couldnt help you out with any suggestions on patching it up.
