I have a 20L tank that I'd like to set up on my computer desk, however there just isn't enough room for the tank and monitor to both be on the desk fully. However, if I leave about 5 inches of the tank hanging off the side of the desk, I can fit everything. Will this stress the tank over time to the point of failure, or will I be alright? Worst case scenario, could I put a piece of wood underneath it to stabilize it?
