In the past I've used an Aqueon medium 5" siphon for my 10 gallon tank. Since then I got an intestinal infection from my fish from getting water in my mouth from sucking to start. I won't do that anymore.. I'm looking to get a starter bulb for the Aqueon or another siphon that has a starter bulb. I've seen Lee's gravel vac that comes with one. I'm looking for people with experience who can comment on 1) a good gravel vac that is actually strong enough to suck up debris but won't clog with gravel, and 2) has an excellent bulb (or otherwise) self starter. 3) works in only 9 gallons of water).
