I'm looking for a tank with at least a 4'x2' footprint, but preferably 6'x2' or larger. New or used as long as it's in decent condition, no leaks. I can go as large as 8'x4' so let me know of you have anything between a 4'x2' and 8'x4' for sale. I can pick up the tank no problem but preferably no farther than 2 hours (3 max) from the Pittsburgh, PA area.
