I just bought a used 125 gallon tank. The tank is older which is the half inch glass and i need to reseal/recork it. how the hell do i do this? I dont wanna mess up and need to do it well! the glass is fine. Its still holding up but its all messed up and need to redo it because the guy before me tried patching it... it looks discusting but i got the tank for a steal so i couldnt let it passs. Please help me out! I cant afford to buy a new tank so please anything will help. Thanks in advance!
