cracked euro mean no water?
 

Does a cracked eurobrace in the front long panel mean your tank can't hold water? 60Lx28Wx29H?

You could make a center brace . I've done that out of aluminum when my glass center brace let go. Had to drain the tank 1/2 way & slip it in & refill .

But to answer your question : Ya , it'll probably hold water till it blows apart .
I was really impressed how much glass can bow !

With 29" high, you'd be asking for trouble eventually. Really depends on the thickness of the glass though..

good luck
 

I once used a few large a wood clamps to support my tank from boing .Then removed brace & all traces of silicone from tank with very fine sandpaper. Replaced brace & silicone without draining tank :smile:
