Powerheads sucking water during water changes

[Bloomk]

Is it ok if my powerheads suck air a little during water changes? I saw an experienced friend of mine do a water change and just let his powerheads suck air and blow bubbles all over while he did the water change. Does this hurt the powerheads or the fish/corals? Or does it just sound bad?

Long as its not long just not supposed to run dry cause they overheat

What would be "not long"?

Imo id say long as its somewhat touching water youd be fine to do a waterchange

I unplug mine when they start to suck air. I'm always afraid the bubbles will irritate the corals.

Some pumps and powerheads will get damaged when run dry. I usually just turn everything but the lights off before doing a water change. Less hassle.
