Mini skimmer too disruptive?

[JasonAz]

Hi, im currently 2 weeks in to cycling my first aquarium which is salt water and 20 gallons. Ive given the mini protien skimmer time to break in, and so far seems to be working properly but i was wonder if its too loud for the fish. From outside the tank its pretty loud and most likely louder in the tank and im wondering if this will stress the fish once they are introduced.
Ived since moved the simmer to the right side of the tank to be away from the power head.
