brace

I have a 210 gallon aquarium (7' x 2' x 2.5') and tonight all of a sudden the 2 braces broke off and fell in the tank. The braces were at ~28 inches and ~56 inches. From what I have read, this could be a sign of aquarium bowing and impending failure, so I am draining half of the water and moving...

I am looking for a ideas on how to make or what to use for a canopy for a 75G no brace. I have even considered making a faux brace just for the glass tops to sit on.

Just filled a 55g, and the center brace has slightly separated (i.e., broken) away from the back edge of the top frame. Does this mean the glass is bowing, or I am in some other danger of all 55g going on the floor??? :eek:

Thanks to a generous fellow CCA'er, I am the new owner of a used 55G. At some point in it's past it appears that the center brace was broken and removed. I filled it to find out if it held water and the good news is that it does. The bad news is that it bows about 3/4" in the center when...
