I have the opportunity to get my dream tank (size) for relatively cheap. It's a 125 gallon tank with stand and canopy. The problem is that, according to the seller, one of the seals leaks water. How hard would it be to reseal a 125 gallon tank? I'm somewhat handy and have watched lots of videos on making/resealing glass tanks, but none have been this large. Should I pull the trigger and trust myself? Or is a 125 gallon glass tank too much trouble to reseal? I would probably want to add some eurobracing (with a center support) to the tank rather than a trim, if possible.
