Well, I had a professional look at it. He declined to do it. But he said it was really easy to do. I asked him why he wouldnt fix it and he avoided answering. I figure he doesnt want to be liable for the seams blowing out and ruining my house
As I said, I removed the broken pane of glass. It took two days, about 5 hours of work each day and a LOT of razor blades. I still haven't got the silicone off the glass. Removing that silicone so the new silicone can properly seal the new pane of glass in place is, imo, next to impossible.
And apparently everyone else thought the same as I tried to GIVE the tank away after no one would buy it for $100 and I couldn't...
So now, I figure busting the tank up with duct tape sealing it is my best option
