It only makes a difference if you get some "suck back" of the liquid from the airlock to the fermenter. I use tap water in my airlock.
I usually wait 2 to 3 weeks to take a gravity reading. I'll have a good idea of what the beer should finish at and how long it should take so for me it is only a verification that the ferment is done and I don't have a stuck ferment.
