There is a huge difference with FOWLR tank and a SPS tank. 40ppm is extremely high for me, fine numbers for fish tank.
Fact: filter socks remove signficant particles. so much that they generally clog up after a week or two. (bad practice was them every few days no soap)
The particals slowly break down resulting in nutrients a good skimmer and husbandry will keep the numbers low. There are many good methods a properly maintained filter sock helps. Are they required no, provided you have a good skimmer/refugium/chemical filters. They are cheap, easy, and effective.
