Took a picture of the dust/dirt this morning. The pool was loaded with it. I was thinking about something else also. My filter runs at 16psi. When I remove the return plug to install panty hose or to fool with the "eye" the filter psi goes to 10. I wonder if that then changes the gpm enough that the filter can't handle the power from the pump and that pushes fine dirt into the pool. Again just grasping at straws. I've had the panty hose on now for a few days and the pool has been without dust/dirt. It hasn't rained so that is ruled out.

This morning I added 1 cup of DE vacuumed and the backwashed. So we'll see what happens next. I also vacuum with the skimmer basket in and the skimmer sock on. This stuff is so fine that it goes right through the skimmer sock...there was a tiny bit of filter sand when I vacuumed but not enough to even be measured.

I've attached a picture.
