I just finally got an all in one insert that included a filter sock. It would clog in a day and restricted flow to the point the return pump almost running dry. I cut coarse blue foam to fit in the sock holder, so now it catches large particles but doesn't impact flow. I only used the filter socks for about 2 weeks before trying the foam. I haven't had to rinse the foam yet and I'm on 2 weeks of it being in there, no reduction of flow. I plan on rinsing the foam when needed but have replacements precut if needed.
