You just clean it every few months. The plants will chow down on any nutrients building up in there. And if you're like me i only use sponges and bio bags in my HOB's, no carbon. Some filter floss every once in a while but I've found that stuff really does too good of a job of filtering(oxymoron?). I have to change it once a month at least because it has collected so much debris.
