I feel stupid for asking this but when I put the airlock on my fermenter, do I put the lid on the airlock, or just put water (or vodka) in it,and leave the lid off.
I put the lid on all mine. I have the three piece and the "S" shaped. Keeps the cat dander out and may slow down evaporation (probably not). Beisdes, you paid for it, right?
The lid just keeps the water or vodka from evaporating quicker and keeps stuff from falling in it. The lid should have little holes in it. You don't have to have it, but it is there for a reason. If you were to not use the lid, it wouldn't be a big deal.
I put the cap on top to keep out debris. I always sanitize the stopper and airlock before putting them on the carboy, but I just use plain tap water, not sanitizer or alcohol in the airlock. Works fine.
Ditto. I put on the top, you wouldn't want it to be in the middle of a heavy ferment and have the cap not go back down, then have some kind of crap fall in there.
I always put the lid on mine. I used to use vodka in my airlocks all the time but now only do it half the time. Tap water works fine for me, and I am with Orfy...drink it in a bloody mary.
