I've been told like a filter media around the pump intake or in a bubble trap but it removes the pods to sign I don't

How low is the water line from your pump ( how deep is it?)

You could have a little whirlpool that's doing it?

 

[reefer77]

about 10 inches

Hmmm that's strange cause the only way is for the pump to suck in air if there's air going in to it or around it or your return to the DT is above water level?

How long have you had it running till it started doing that?

 

[reefer77]

been doing it since day one about a year.

Air getting in via the plumbing some where?

Bingo! Its sucking in air from somewhere along the line.
