After setting up an old 55 gallon aquarium, I noticed that the top frame is cracked. the crack goes through the entire frame. As of right now, the tank is holding water with no issues. Ultimately I will replace this (a LFS sells them), but will the aquarium be fine until I get around to it, or should I drain it right away? It will probably be a few weeks before I can get around to replacing the frame.
Also, how do I replace it?
