Take off motor assembly, check impeller and clean. It can be a combination of media too, make sure the baskets have plenty of space to lock in.
If all else fails try taking all the media out and see if u still have bubbles then just re arrange. Make sure that little tiny tube on the lid isn't clogged that's what auto purges it every 24 hours
