I may be wrong, if I am someone will correct me.
I got a used Oceanic 180 last year. I don't know how old it was. When a couple of the fellow club members came over to see it, They told me how, AGA took over, or bought Oceanic, something like that. Because they were a little surprised that I had an actual Oceanic. They told me if a person can find a real Oceanic tank, (before AGA took over Oceanic, then that person has a very good tank. Something to that effect.
I do have an Oceanic 180 gal RR tank, except for a few minor scratches it is in great shape. I love my tank!
