I was sitting home the other night when I heard a loud pop sound come from my 55 gal. salt water tank. Didn't think much of it until I looked over and saw the sides starting to bow out. What had happened was the piece that holds the back and front had snapped and I think it was just a matter of minutes before the tank gave way and emptied onto my living room floor. Has this happened to anyone else here or is it just my luck?
