BubbleMagus z6 Noise

[TheSheff]

Hello, I attached a video of the “issue” i’m having. I just setup this bubble magus z6 protein skimmer and for some reason there is this really weird noise coming from the output of the venturi tubing regardless of the airline valve I use. I am just curious if anyone else may know how to fix this or make it better. Thanks!

It almost sounds like its not getting enough water. Can you send a longer video
