I used to be afraid of siphons, after failures trying them in the past. But now I have a siphon with a hand pump at the end, so it's very easy to start, and no worry about sucking tank water! Definitely recommend the Python brand (I don't have the water changer, just the siphon). I also place my bucket on a chair just a little lower than the tank, so I don't have to dead lift it from the ground. Much easier that way!
