Right now in my AC 110/500 I just have a sponge and ceramic rings.. I was thinking of removing the ceramic rings and adding a different media.. What do you use?

If you do keep it, I’d get rid of the sponges. Unless you are cleaning them with get frequency, they just trap stuff. Let the biology in the tank/sump/refugium “eat” this stuff and get rid of it.
