Just go to your local pet store and get an aquarium siphon/gravel vac that states self siphoning. If you cant find one that's cool to, the regular ones work just fine!
Put the one side of the tube in the bucket and place the other side "the siphon side" in the tank. Tip the siphon under the water till all the air bubble have left. While making sure that no air gets into the siphon point the one side towards the sand/media. Then start making a pumping motion with your hand. Walla! you have a siphon and no salty mouth!
The video is a little long but it explains what I just sail well enough along with another method..

Ps. If you can afford a python system awesome! I loved mine till I moved. The new house dons't have enough water pressure to make it work.
