Tank trouble

I bought a used 55 gl and the middle bracket was broken. I thought I had it fixed with epoxy glue but one side snapped again. It held for almost 3 days. The tank bows out about 3/8" in the middle. The glass is 7/16" thick and I'm wondering if bowing that much will be a problem. I cannot think of another way to fix it besides making a bracket of some sort that would lap over the sides and hold it in place but even that I'm not sure what I could use. I don't know if the people who had it before had let it bow out or if it had just broke. It kinda scares me to have it bowing.

Any suggestion would be greatly appreciated. Thanks

It's broken right were it touches the glass. I don't think there is any thing I can screw into that would hold. I'm going to Home Depot later today to see if I can find something. Maybe a srip of 1/4" metal that can be bent at both ends and glued on?

I wish I had just bought a new tank:idea2:

Thanks for all the replies.

I went ahead and got a stainless steel metal strip and bent and glued it in place. I re-epoxyed the brace back together and the put silicone on top of that. The metal strip I used don't look too bad. All you see is a 1 1/2" x 1" metal piece in the middle of the tank. I might get some paint and try to match the trim. So HOPEFULLY that will hold. Only time will tell.

I figured it would probably be OK bowing a little bit but just to be on the safe side I thought I'd try. The Emperor 400 puts out a decent current( I think thats why it snapped this last time. I had put the filter on the same day) and the tanks only 12 1/2" wide.

Thanks again, If it breaks again I'll check into getting the whole piece. I didn't know you could buy those. How much was it?
