Vodka is perfect! Some use a sanitizer mix, and some use plain water. Those are all fine, as long as you remember that sometimes the liquid in the fermenter can be sucked back (via vacuum pressure, like in weather changes) into the fermenter. So, anything that would be relatively benign to your beer would be a good choice. Don't use bleach, for example.

Yes, vodka!

bacteria won't grow in it. and if there is any suck back into the carboy it will just add to your ABV!

Some people even put just aluminum foil over the top for the primary.

I personally use Stan San mixed with water.

I usually start with Vodka but if the level lowers at all, I will fill it up with a couple squirts from my idophor sanitizer bottle.

My friend uses salt water.

He has a fruit fly problem and they can get in the lock through the little holes and lay eggs. Then the next generation gets in your fermentor while they are maggots. I have seen this.

I use water.

I probably will not be around much anymore. I had to close my restaurant and get a real job so i do not have the time to hang out online all day.

I normally use sanitizer (iodophor) water that was left over from when I sanitized my brewing equipment. It gets renewed when I move to secondary.
