You can do it that way too...but...eww! lol! You only need to do it that way if you can only get one end in (like a gas tank) but in a pool or aquarium or other large container just submerge the whole hose like I said.
My hubby said you can also get a cheap siphon hose in the automotive department at Walmart...no idea what size it would be, but it might be worth checking.
Glad I could help!
