The closer I get to the day I can move into my new apartment, the more worried I get about my tank. It's a 70gal all glass tank, that has been empty for about a month while I was adding a rock abckground. I know the tank held water fine for aver a year, but I am worried that the added rocks/time without water may have done something to the seals. It was indoors the whole time...I just want to be as sure as I can that me new apartment won't turn into my new indoor swimming pool...
