Sorry, I didn't scroll down.
The water height should be at the wavy line that is half way up the neck, just below the cup. It will take several days to a month or more - - oh wait I see another wavy line!
Yeah, someone else will have to tell you the appropriate water height. But it'll take some time to break-in. I had an eshopps skimmer (pos) that took almost 2 months to break-in.
