Disaster Narrowly Averted

[Palster]

Last night when I went downstairs to feed my fish while I was opening the hood I noticed that it didn't seem to fit right. When I opened the hood I found out why. The center brace (which is a piece of glass siliconed across the middle) had let go on one side causing the glass to bow out quite substantially at the front and back. I immediately went and got one of my wood working clamps to clamp the glass back to the center brace. This seems to be holding everything for now but my dilemma is whether to try and fix this tank or to buy another one. The tank is a 135 gallon and I have been thinking of moving up to a 180 gallon someday. I guess the only good news is my wife is quite concerned about this tank letting go again if I was to fix it myself so she is reluctantly in favor of me buying another tank which means I would probably go for a 180. Has anyone had any luck repairing the center brace on a 6 foot tank and if so how did you do it? I assume the tank would have to be drained.
