Thanks Guys,
I am really trying to find something I do not have to modify much. I want the tank easy to access so, a 70 or 90 gallon is not going to work. But Kemist, that is an interesting idea.
Moovin, thanks for the link. That guy has a lot of different size tanks for sale. He even has a few exactly what I am looking for, 1 inch and rimless with free shipping. A little more than I want to spend right now though.
