I have this Brown Siphon, and it does its work when I tell it to.

Each time I do different parts of the tank, so I don't think the bacteria would be affected. In any case, my sandbed is 3" thick, so sticking in 1" should not make that much of a difference. I have been doing this for 5 years and there does not seem to be any adverse effects. You should see the dirt that is sucked out especially when the siphon is inside the sand.
