This is where it gets tricky. I do not use socks, I let the tank consume most things. By tank I am referring to all of the corals, nems, microfauna, hermits, sponges, snails, etc. etc. that consume most organics that are present in all the stuff that can float around. In my sump, I never vacuum it. The pods and other stuff eat most of it and the mulm that results from detritus sitting there is a home for worms and other critters. Also, most of the detritus that accumulates in a sump is inert and doesn't contribute to nutrients once it has settled and been gone though by the worms and such.
This is the method I use though and it may not work for all. Especially if you want super clear water. While my water is super clear (no tint to it) and the fish do look like they are floating in the air, the stuff being blown around also does.
That is one of the things I love about this hobby though, many many ways to make out little glass boxes thrive. Some run a super clean (as in no particles everywhere) tank and other (like me) let it ride with all the stuff that does float/get blown around.
In short, I just have a lot of things that eat the stuff, so leave it there to be eaten lol.
