I rotate about 5 socks on my main tank and 3 on my nano. I use the 4" x 9" ones. When they start to overflow/clog, I switch them out, rinse them under hot water and then store in a bucket of water with 1/2 cup of bleach in it. I keep adding socks until about 5 are dirty between the two tanks and then rinse them again to remove the bleach, and wash in cold water(in the washing machine with vinegar).

They usually come out looking close to new.
