Turns out this tank is already drilled and there is some sort of a stained glass background that the previous owner glued on. The guy I talked to said there really hasn't been any interest in it and he wants it gone so I think I might be able to get it for 50. I'm going to check it out on thursday I'll see if he'll do a leak test for me and I'll check out the back glass situation.
I have a new question. Now assuming I go with this 75 I should get a bigger return pump correct?
