There's a company out of Pasadena that builds tanks. I don't remember the name, but John over at Global sent my 75 oceanic to them to have the huge center brace removed and strips of glass put around the inside edge to make it a eurobraced tank. It took about a month, but it only cost $30.
I'd contact John and ask him.
