i have a question I have 2 filter socks in my 135g with a 40g sump and the water just goes over them. They are not clogged either. Nave I should try the pantyhose lol.I think some run them through clothes washers too. That was my gameplan. I'm not sure I want fish waste in with my dishes. This is new to me, so we will see...
I have heard to wash them in the washing machine with some bleach. I quite using mine because I found one of my fish inside the sock dead water I guess use to strong in there and he could not get out and killed him. So I quite using mine after that.
+1 washing machine. Once every few months I use very small amounts of bleach (no detergent) to make them like new again. (There's no real benefit here, just personal preference.) When I do this, I do another cycle with just hot water to rinse the bleach off.
I have a 135g dt with a 40g sump. I keep 4 socks on hand and rotate them. I wash in washer with a little bleach then flip inside out and run them again. This time no bleach, just rinse and spin. Works well for me. I find myself changing them out every 4-5 days.
