CichofitAll;1923891; said:I had this problem on a 60G. My solution was to get a piece of glass cut that was a hair under the tank width(front to back), and 6 inches wide by .25 inches thick. Then I used silicone to glue it in place just under where the cracked brace is. I let cure for a week then filled the tank. I had no measurable bowing and it has held for over a year with no problems.
Thanks for the idea, This seems alot easier than buying another whole top bracing for the aquarium.
I'll have to look around town to see if anywhere sells glass.
Does anyone even know or attempted to take of the top plastic bracing of a tank?
