so i come home yesterday to find my 50 gallon tank center brace had gave out, and the tank had a "belly". i didnt know glass was that flexable i wanna say it flexed like inch i didnt measure so give or take a bit. so i had to set up an e-tank and drained almost all the water out of the tank just left enouf to keep the plants wet. so after a bit of research, mostly on what kind of silicone to use, im going to try to fix the tank today. if anybody has already been thou this any advice or tips would be greatly appreciated. so ill keep you guys up to date on the this issue. im just glad the glass didnt give imagine 50 gallons of water in your living room floor and to make things worst im the 2nd floor.
