Is there any possible way of fixing a crack in a glass aquarium? The crack is in the back right side of my 75 gallon fish tank that I just got from my brother. I believe it cracked during transport somehow. It is on the back glass towards the bottom and "V's" out about 4 or 5 inches from the side. Am I still able to to use the tank? Do I trust that it will not break any further or do I try and fix it somehow? My only other thought is that I have to get a brand new tank which I fell is gonna have to happen. I have attached some images of the crack.
