How do you start your siphon?

I suck on my hand, which I use to make a cup on the end of the tube of the grabel vac. I don't suck until the water hits my mouth. I suck until the water reaches about 3/4 of the length of the hose, then the water pressure takes over and starts siphoning.

To me, it's much easier than shaking the vac up and down in the water and creating a tsunami in the tank.
 
My gravel vacuum uses the one way valve 'bob' method which is great for removing water, but my container for treating replacement water has an opening which the vacuum wont fit into so I have to remove it and use the old gasoline thief method!! Never got caught yet with a mouthful of dodgy water!
 
I just suck on the end of the hose; I used to live in Korea, so I've probably drank dirtier water from the tap than what's in my tank.
 
I figured out the method Sammie7 describes a long time ago--there had to be an alternative to mouth-siphon. Works like a charm every time, little to no agitation in tank aside from tube vac action. No-brainer.:)
 
i DO use my mouth. I put my shirt over the actual tube and suck on it. as soon as you see the water come up the siphon tube and start on its way down the tube, you can take your mouth off and the pressure will do the rest. I've never gotten water in my mouth.

It's really simple and you don't have to spend money on any additional equipment. if you get a mouthful of water, you need to stop sucking so bad. hehe.

and i don't think its gross. i love my fish! poop and all
 


Siphon bulbs are for pansies.

Besides, a DIY from Orchard easily can be made for 1/4 the cost of anything from petco, petsmart, LFS. Pythons waste water. I like the fully submerged tube method myself, and since I use bucket to change my water, the tube is only about 6' long, if that. And I have yet to suck a mouthful with the blowjob method. I just don't swing that way.
