a tanks bottom bursting out?!? WTF. a tank that big would have to reinforce the glass. i don't see how a electric problem vcould do this. this is'nt right. you should talk to the tank manufactioners. sorry about your pacs. i now how bad it is. i have had my favorates, and i have had a couple that i loved and were part of the family in a way. my trained electric catfish. i petted that thing, taught it to swim through hopes for food. if i layed my palm flat on the bottom, it would come and sit onit, and let me move it. amazing how fish can bond sometimes. i gave that thing a burual in the backyard right next to my cats. it happened a year or 2 ago, and ever since, i have been searching for another, but for some people, they lose interest in that type all together agfter they lose a fish that great to them.good luck. u must have a lot of work to do
