I also tried to take a video but cant hear this sound in video.

Is it actually starting and stopping or is it just making a sound? How many turns out on the nozzle do you have it from fully closed? What is the sump depth? How old is the skimmer and when was the last time you took it fully apart for a thorough cleaning? I’d take it complete apart. Do a thorough cleaning per the instructions in this thread. Make sure you inspect the venturi port on the nozzle for salt creep. If I had to guess, I’d suspect it could either be the pump needing cleaning or that you need to open the nozzle more as that will cause surging and can make a bit of noise if the pumps not getting enough air.
Follow the cleaning instructions in this thread and be sure to clean the bearing as per post #2.
