"Pearling" after water changes, with no plants, is a horse of a
different color. I'm assuming you are referring to the air bubbles
that appear on the aquarium glass when a big water change is made.
Those bubbles just appear and remain there until they break loose and
disappear. Real pearling will involve streams of bubbles coming from
plants, or, if the glass "pearled" there would be streams of bubbles
coming off the glass walls.
