Just bought a bunch of 200 micron filter socks for $2.76 each. They have the Berlin plastic ring and fit my Hang-On Acrylic Mount. They are 4 inches x 12 inches. Arrived in a few days.

These are the model I bought
100 Micron 12 inch Filter Sock - PONG100P4P
You have to buy 25 of them at a time to get this price, but I figured having several on hand means I won't have any excuses keeping a clean on in my sump.
