Power Head sound

[ZachariahBeanz]

Hi, I’ve recently noticed my power head I bought a couple weeks ago seems to be making a bit more noise over the last couple of days. It’s nothing much, just a small but slightly louder noise than usual. Is this okay?

Have you tried cleaning it?

I've had tiny snails get into mine and it makes a lot of noise. I've also left one running in reverse, and it made a lot of noise until I discovered what was going on in the app.
