I can’t speak for theMeat, but I don’t run socks either. I have a Triton style sump with fuge first with Miracle mud, chaeto and caulerpa in it. Skimmer is in second chamber. Got tired of messing with socks and wanted to try this style of sump. Been working great so far, swapped it out about 2 months ago. What little detritus i see is usually in the Chaeto and gets removed when I thin it out every week or so. Tons of snails, copepods/amphipods, worms, stars keep it clean. Wanted a more natural way of filtration and less maintenance.
