I have a used 30 gallon tank and now it is starting to leak slightly. The black strip on the bottom of the tank that supports the glass is loose in the front of the tank and it is slowly seeping some water. I'm not sure what to do and hope that this isn't a serious problem. I don't want to come home one day and find that the tank has collapsed from the weight of the water!!! Should i get some glue or something better for this? Or scrap the tank and get a bigger one?!?!
