I personally don't run either anymore--sponges or filter media and or a micron filter sock.
They have the ability to trap nitrates and release them back into the water column
this is because they can't support anoxic bacteria--the bacteria responsible for breaking down nitrates to nitrogen gas--thus completing the nitrogen cycle.
This includes trickle filters with or without bioballs, fluvals, canister filters ect ect.
Best to remove all the media where possible nitrates can collect.

I prefer my substrates stirred but not shaken
