so i got that 180 with the cracked back.... i have been trying to figure out a way to fix it good.. i just had the idea.. since the crack is very close to the corner could i just box the corner off lika an overflow and reseal the crack then i can drill a hole in the side right at the bottom run a bulkhead and i will have a corner overflow.. this would take alot of the pressure off of the glass since there isnt as much water in the overflow.... does this make sense??? and would it work????
