I learned 2 things with these filter socks. Firstly, I have no idea about the size (when I first ordered shorts because 8 inches sounded like a reasonable size compared to what my eyesight told me). Second, pet stores lie to you. now that they are 20. I thought you really had to work to get the life out of them. Man I won't miss cleaning some monthly filter socks (and it's a 175g kid's pool so that was a daily clean). I'm having trouble figuring out if the products I need are in your company right now because I know they will work well and be priced right.
