I'm a little confused about "media". You don't mean a substrate, do you? If so, I would avoid Miracle Mud; I think it's been behind my ongoing algae battle, check out my phosphate leaking thread if you want.
Otherwise, I'm not a big media fan. I have bioballs in a baffle directly below my overflow pour just to break the flow up so it doesn't bowl my macro's over, but they aren't there for biological purposes; the emperor 400 and the live rock do that.
Any problems in the tank? Algae issues?
