Happens all the time when it rains here. Even more noticeable when no one is in the pool for a day. The current from the return will basically push it to the same spots each time. If you chemical levels are in line, try to vacuum as needed and enjoy the pool.Quote:

This is just the first year, although last year I had a sand leak problem so it could have happened then and I wouldn't have noticed as much because it would have mixed in with the larger pieces of sand.
Also this summer we've gotten so much rain. Grass is still green without any sprinkler watering. Usually by this time the grass in our backyard is burnt.
This is exactly how mine looked after shocking with the Calcium hypo shock, only worse. Did you try vacuuming and using just bleach? I don't know if it is just the calcium falling out of suspension or some precipitate from an interaction with something else in the water. What I find interesting is that it didn't happen the 1st year with the pool. But once I got the mustard algae I was going through bags of shock to try and kill it. Finally killed the algae but from then on (and even this year) I would get a whitish gray fine sediment anytime I use the Cal Hypo Shock. I have used bleach since then but just to prove out my theory I bought a couple bags of lithium hypo shock and they also dissolved instantly with no residual. My only guess is maybe it has something to do with TDS as that is the only number that is high from my pool water.:confused: :confused: :confused:Quote:

I would vacuum at night and the next morning it was basically all over again. If the sediment is basically in the same area and you have one of the "eyeball" returns you can try pointing it in a different direction and see if the sediment "moves" to a different spot b/c of the current change.Quote:

I think it is (was!). We vacuumed it up and then it was back the next day but not as heavy. Waited a couple days and vacuumed again last night. This morning there is not a speck to be found. I imagine it was just excess DE that the filter didn't need. I was worried my filter was malfunctioning, but now I think probably not.Quote:

Could also have been one of those "weird startup things" that happens - like the sand washing out of a newly loaded sand filter.
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.
