Thanks. I used those to set up the skimmer. Unfortunately, I don't know what I'm looking for I terms of signs that I have it tuned correctly as I've never used a skimmer before.
I've read that I should aim to have the bubbles in the neck twice the size of the ones in chamber. These seem too big. But I can't turn the air down anymore.
I also verified that the water level is perfect for this brand of skimmer.
Here's an attempt.
