To clean filter socks(Stole this from Reefer Gil)- Turn them inside-out, throw them in a bucket, and add 2 caps of bleach. Fill the bucket up with water and let it sit for 12+ hours. Take it out, rinse them real good with a water hose so they're white and the bleach smell is gone. Let them dry for at least 2 hours and they're ready to be used again. You can get by with 4 filter socks. When 2 of them are dirty, clean them and use the other two.
I really want to keep this topic going!
