I use a homemade 'Python' for the 55 and the good old siphon and bucket for the 10 gallon. All you guys talking about buying a Python, look into making your own. It's easy and cheap. You'll need a waterbed fill kit for the sink attachment, (if you look at it and then compare it to the Python you will see it is exactly the same except a different color) some nylon tubing in the appropriate diameter (I got some made for restaraunt use) and you'll need fittings. Get plastic compression fittings and not the metal 'screw and strap' kind of hose clamps. The only Python brand part I'd consider buying is the plastic shutoff valve if you can't find one like it in your hardware store. It's a real nice thing to have and I'm kicking myself for not putting one on mine. I think I'll be making some modifications to it soon! The nice thing about it besides the money I saved is I just saved the shorter piece of tubing that came with the gravel siphon I was already using before I got the 55 and I switch the siphon back and forth to do each tank.
Whoever it was that said they need a bucket, a 5 gallon pail is only a little over $3 at Wally World...get one, or better yet two! They are brand new so you don't have to worry about what was in them before.
