Filter sock... Yes or no?

I voted for sponge but actually use polly wool (pillow stuffing stuff). I put a handfull in my over flow and change out weekly. Cleans up water great and just throw away when dirty. Get it in big bags at local sewing store cheap. Just make sure it is not hypoalergetic and or mildew resistant as i imagine it has some sort of chemicals in it. LFS does sell it as well but it is more pricey

I'm lazy, I use filter floss after the skimmer. I change it when it stops passing enough water, usually about once every 10 days. After that i throw it out, costs maybe $5 every 2 months for the floss. Way easier than cleaning socks only to have them to clog up in 2 days again. It's been working great, my tank has never been better.
