My 75 gallon tank leaked out, so I have been keeping my haps temporarily in a divided 40 gallon tank, and I was going to set up my spare 55 gallon tank for them today, but I realized that the frame is cracked in two places, it's cracked on both of the corners on the back of the tank. Is it safe to use? I'm going to hold off on setting it up until I know if it's safe to fill up or not.
