What Kind of media do you use in your sump?

[Coderad]

I am planning on taking off the canister filter and just adding a sump or fuge which would be more benificail for keeping the tank clean?
What would be the best media to keeping in it is what I am trying to figure out.
No media at all, just live rock rubble, Mirical mud, make it into a fuge and add plants. Which is the best way to go?
I want to keep my tank looking clean,
But I want to get away from the weekly filter cleanings.
My tank is a FOWLR now but I am planning on making it into a reef eventually.

Thanks for all of your input everyone, I just want to know the best way to set it up so I only have to do it once.
