I have a turboflotor and I can make it do what your does in the video. BTW, I don't have any adjustment on my air intake line.
With the turboflotor you really just have 2 or 3 adjustment you can make.
One is thing that affects the hieght or rise of the water is how much of the skimmer is below water.
Then you have three adjustment you can make. One is the valve on the water coming into the skimmer, mine has a grey valve that came built into the inlet water pipe. If you turn this off completely it should not rise at all. You will need to just play with this depending on how much water pressure you have coming in.
Then you have two grey valves built into the two outlet tubes, you need to twist and pull up on these to see which way the opening point (remove them). Then just pust them back in and adjust right to left on both of them till you get a water level steady on the side of the cone, but not overflowing into the collection cup. If you can't stop this overflow, with these 3 adjustment you have something plumbed wrong.
BTW I have the older RIO 2100 pump on mine, not the newer oceanrunner.
But when you do get it right, it will need some break-in time .
Just wondering where is your water coming into skimmer from? gravity of a overflow?
