The best bio media is live rock.

Other medias such as bio balls/bale work good to keep ammonia and nitrites down, but you have to be diligent in keeping the media clean or your nitrates will sky rocket. There are other medias like seachem matrix that supposedly work even better then bio balls/bale. You can use it passively like a substrate in a sump or through a fluidized chamber. However, the problem with fluidized chambers is that if power goes out on them too long such as with a power outage, you can kill the entire bacteria colony in it.

good question deadhead. so paradox are you saying that i should use live rock instead of a filter? im guessing im readin that wrong, but i wanna make sure i put the right gear in the sump im building. if i need a filter too, should i put the live rock before or after the filter in the sump? and should i put the skimmer first or after the filter/live rock? sorry. lots of questions. this is gonna be my first octo, and i wanna make sure its done right.

Live rock can go in the main aquarium so that your friend has some hiding places. You don't need an additional filter if you have enough live rock - usually 1-1/2 pounds per gallon. The skimmer should go in the sump along with the heater.

Yup. That's what they are built to do. :smile:
