I find that filter socks plug up too quickly for constant use. After a few days, they become merely a method of minimizing bubbles from the drain effluent, which isn't a bad second function. I use them to polish the water every week for a day. Polyester fiber fill works with weekly (or sooner) changing.
Back when we didn't have adequate means of importing nutrients for invertebrates, mechanical filters were taboo, as they robbed corals of suspended foods (primarily detritus). With todays viable foods like zooplankton, phytoplankton, Polyp Labs Reef Roids, Argents Cyclops, and DT's products we no longer need to rely on suspended detritus to feed our corals.
Modern flow patterns and rates also keep foods suspended longer so corals get a fair chance to utilize nutrients before they're exported or trapped. With these new flow dynamics comes a subsequent demand to mechanically remove an excess of suspended matter.
I use a flow rate of 20-40 times the volume of the tank, along with Oceans Motions 4-Way wave generators. The side effect is a snow globe appearance due to suspended detritus (marine snow of sorts). This is a good thing, as I no longer have detritus settling in the substrate. In the absence of a mechanical filter, detritus is exported by the protein skimmer, but it can only remove so much. As a result the refugium & sump becomes a mechanical filter by default.
Another practice is to use detrivores in you sump. Some people use hitchhikers like crabs and starfish (particularly the green ones that eat fish), while others use assorted benthic invertebrates like worms, squirts, and sponges. A conspecific zone can be maintained with xenia, anemones, or colonial polyps to reduce & remove detritus as it becomes available in the sump or overflow.
Regardless of how you set it up, your going to have to roll up your sleeves eventually, but we all want to delay that as much as possible.
