I probably won't be able to re start my long 20g for a few months due to me being short on cash. The water has soured and smells kinda bad so I would like to empty the tank complety. I have heard storys of where after the tank is filled up and then emptied for months the the seams holding the glass together become weak and the tank being as sturdy and stable as a very old woman on a pogo stick. So will the tank be ok if I empty it for a few months or not?
