By settling, I mean detritus resting on the sand bed and making it look ugly. The sand bed itself has lots of nutrients trapped which will not get released unless you disturb it. And over time, the fauna in the sand bed takes care of it. The fauna is more important to me (pods, bristle worms). Why don't people take out all the LR or give a shake and take out the detritus? I am pretty sure those crevice and crannies can undergo some maintenance too
