I was at my lfs and the owner told me I didn’t really need to have a filter sock in my system. My tank was started last November and my bio load is lite only four fish and so invertebrates. I had a filter sock in for a while but my sump is kinda lacking in space with my protein skimmer. For the last month I’ve gone without a sock and the tank seems clear. My perimeters are good. I thought about making one of those rotor tube filters. Any thoughts or suggestions?
