Hi Dave,
I also have a 55 gal. & do it the same way that you do. The only exception is that I put in all the water conditioner I'm going to use in the first pitcher of water. While it's in the tank it works for all the other pitchers of water I end up adding.
I hope to be getting a python soon. It's a hose contraption that hooks up to your water faucet. It drains & then fills your tank back up. It doesn't fit all faucets, but you can buy an attachment to make it fit yours. There is also DIY info. if you want to make your own from parts. Also water bed filling kits are supposed to be either the same thing or similar. I've heard these pythons are in certain pet stores & even the occasional Wal-Mart. You can look all this up on the net... Good luck!
