I cleared out the 1/8" of gravel and dried fish poop out of my 145-150 gallon that I just bought and was cleaning it to start to reseal it but I noticed a crack on the bottom pane of glass from one side to the other short wise not tank length. I looked on the bottom of the glass and no crack because I felt the glass. I think there are two panes of glass for the bottom because I can see lil water like puddles under the glass but not on the floor. My main concern is what do I do. I am filling it right now to see if it busts but what if it doesn't? How do I sleep at night? Should I buy a new pane of glass?? I need help fast.
