I've only ever had little freshwater tanks, so all I really ever needed for a water change was an empty milk jug. With my 55 gallon reef, I'm finding that very cumbersome. Surely there is a more efficient way to do this, but I'm not quite sure what I am looking for- something to pump the water into a bucket that I can turn on and off quickly, and likely can use to pump the new water from a bucket into the tank.
