Help with this noise

[AdamS]

Hi Everyone.

I am having some issues with pool (mainly I think I have leak again) but my wife just sent this video, can someone tell me what they think this noise is:

Pool filter noise - YouTube

I put on YouTube because not sure how else to post video. I'm good with the water chemistry of the pool but the filter and this area I am kind of clueless. Thanks for your help.

Most likely is a small stone in the impeller housing. You probably wouldnt be able to see it from the pump basket but it should eventually be drawn through although i wouldnt let it rattle around in there too long so you dont damage the impeller.

The second and much less likely cause is cavitation. What is the flow like from the returns and into the skimmers?
