No bucket water changes. How do you do it?

I am curious to know how you guys do no bucket water changes. I have been keeping fish for five and a half years and carrying 5 gallon buckets around bothers my back, and it also makes me really tired. The time it takes when hauling buckets is also a pain and I want to cut my water change time in half if not more. I plan on buying a python siphon for my freshwater, but obviously with saltwater you can't just connect to the tap to fill the tank back up. So I want to know how you guys do your water changes without buckets with your reefs? It will definitely make maintenance easier for me.
