I have a bulkhead in the back, 1" with an elbow pointing down and a straight section that almost touches the bottom. There is a valve outside the bulkhead, I just turn that and get full siphon and the tank drains really fast down to about 1". There wasn't need to glue it either, so I can take it out when I want just a slip fit bulkhead.
