I got fine sponges in the bottom basket, Bio rings in the middle, and in top basket more Bio rings in one half and ammo chips in the other, so the media shouldn't be a factor.
I had the same issue with my old 404 ... check the impeller cover. On my old 404, one of the clips kept coming loose with would cause a vibrating rattle and a decrease in flow.
