I read a lot about using filter socks but where do they go? I bought some and can't figure out if I'm suppose to put it on the skimmer basket that is attached to my small filter or to put it around the filter itself with the extra sock going in the hole that the skimmer basket fits on? I have to make a profile yet but I will just say I have a 10 x 30 " small above ground summer wave pool. Thanks
