So you're running 7" or 8" socks, right
I'm running 300 micron 4" socks. 3 of them at a time. I have 9
When 6 are dirty, I machine wash them. I've stopped bleaching this last time to see how long they last as the bleach use every 2 days may add up

I'm still going through 3 a day, with no fish
I think mine plug up right now as my sand and rocks are new enough to keep adding silt and epoxy residue to the water column ( CUC disturbances )
I hope this is the case
