When I got my 225 AGA, it too had a 24" center brace. Fortunatly, there is a tank manufacture nearby, and I took the tank to them, and they removed the center brace, and installed a 3/4" thick, 4" wide combing around the tank similar to what is found on acrylic tanks, and since it was there, they also drilled the 6 holes in the back glass for my 3 closed-loop circulation pumps. All told, I spent an extra 320.00 for this to be done (included the 6 1" bulkheads, I also had the weirs removed, and entire tank resealed). And I could not be happier with the results from this investment. Tanks been running now almost 2 yrs, and not a single problem. HTH
