The one task I truly hate is cleaning filter socks. When I built my new sump for the 400g, I included a filter sock hanger and purchased four socks to rotate through as needed. These are the large 7" filter socks, not the smaller 4" type. I use a 10 micron sock when I treat the system with Phosphate Rx.
