I have an old 120 I was going to use as a sump in the basement. As you can see there is damage where a previous owner removed baffles and left cracks and gouges out of the acrylic. I was going to patch all these with weld on and 1/4" acrylic before adding my own baffles back in, but I wanted a second opinion. Is this tank a lost cause, or should nice large patches do the trick?
