Cavitation never occurs on the outlet of a pump. The symptom of
cavitation is noise, not bubbles. Still, leaks in the pump housing might
allow air to leak in. Checking for plugged input is a good maintenance
habit to get into.
What'smore this can be real trouble 'sides inefficient energy use and
potential pump/plumbing damage; there is a risk of "gas bubble disease" aka
emphysematosis... you might want to leave the system off, discharge water only
over falls till you get the problem remedied... gas supersaturation can be
detected via a dissolved oxygen (or total gas, or...) measuring
device/technique, visible bubbles under the skin of your fish livestock
(ouch!) or outright anomalous loss...
