My water change progression is as follows:
1) I did the bucket method only once on my 55.
2) 30G storage bin, would pump from sink to bin, condition the water, siphon the tank water into my front yard, pump the bin water into the tank.
This was not too bad, it just took about an hour and required a fair amount of gear.
3) DIY Python using a garden hose and a water bed filler/drainer. Siphon tank water into sink, using a strainer just in case, then refill from sink to tank adding a cap of conditioner before the refill.
Takes about 30 minutes, only uses a 20' hose and the sink adapter. It will be a little trickier in the winter, I'll have to confirm the temp and adjust the sink a few times. It is so easy now to change the water I want a bigger tank.
