1) If you haven't had it that long then it needs to 'break in'. Wear off all the oils that are left from the manufacturing process. Once that happens (few days/weeks) then the bubbles will start to stick to the sides and climb toward the cup.
2) If the bubbles are too far up the neck, there is usually an air tube (ventri) that you can use to control the water height. The more you restrict the air the higher the water level (or the opposite, I can't remember after all this time). So it may be crimped or need to be short of a mod
Or a combination of the two.
I don't have your skimmer, so those are just some general guidelines
If I wanted someone to 'tag along' I'd buy a wagon.
I despise skinny felines!
