Yeah agreed, I only have 4 fish on my 180, and the socks clog in about a week. I've only run a sock on my Berlin side of my sump, refugium side doesn't get one.
Been sock-less for about 2 months, only because they fell apart and haven't been able to replace them, but they do help to keep the sump clean, high maintenance as they are.
