So what options are out there for a 4" filter sock that doesn't run $10+ each or isn't complete garbage? This sump takes 4, so need 12-16 total... I prefer 300 micron, but most felt ones I seem to find are in the 200-225 range. The need to fit a Waterbox sump, and so far I've tried the following
Aquatic Experts 200 micron 8.5 in and 10.5 in- mixed results. 1st order they didn't fit. It has to do with the way they stich the side seam and the felt to the ring. Ordered a 2nd batch and could get them in, snug fit and have to put the seam side in first then the far side, but the 2nd batch stitching started coming loose after about 3 trips through the wash (front load, gentle cycle, quick wash with no spin X 2 each wash).
Eshopps 4" 300 micron 10.5 in - Liked better, like the OEM socks that came with it, looks like melt/crimp ring and felt but the rings are every so slightly too large to fit right. Not sure if I got an odd batch or if theirs really is about 1/8" too large to fit.
Encompass All 200 micron 9.5 in - I had high hopes until I took one out of the bag, fibers fall off the 'felt' and after one trip through the wash they were falling apart.
