I've already got a bunch of scrubbies for it, but I've been thinking of changing the media a little. Last time I used all scrubbies, but was thinking to use ceramic rings submerged in the water and scrubbies above the water line..I always hear/see people talking how scrubbies don't do well submerged in water.
The only reason i leave my sump running is because my tank is drilled with overflows, and i also have a fluidized bed filter running in it.
