Any ideas on how on permanent solution for a fine grit that is not caught by sand filter? We constantly have a fine layer of dirt that settles on bottom of the pool and gathers in spots especially where liner not perfectly flat. If you come near it with a vacuum or step near it just clouds up and disappears into the water. I don't think my sand filter is taking it out well and it just resettles. We vacuum it up but 2 days later it is back. I think part of it is coming from the large flour mill that we live next door to. My chemistry is perfect. Water is clear and we can easily see this stuff settled on the bottom. If I add DE to my sand filter my pressure goes way up fast so assume it is collecting it but I can't keep adding DE constantly as I would be backwashing every time I turn the filter on.
Our city water is awful and rusty too so that doesn't help. We have a house water filter and our fill water is now going through that too but the filter will go from white to rust in a matter of several days.
We did replace the sand in the filter this year hoping it helps and not hurt? (Yes I know the sand never needs replaced but was going to deep clean the sand before start up and assembly was on so tight when we tried to get the part up the whole latteral assembly came up out of the sand. Couldn't get it back down in sand so vacuumed the sand out and instead of trying to figure out how to get the wet sand back in just went with new dry sand that was really easy to pour from the bag) I will say the sand had pool store chemicals ran through it as previous owners did not use TTP. I found TTP when I couldn't get water to clear after buying the house and after 2 pool stores nothing worked. Yes I used the expensive stuff they sold me with no help before I found TTP. TTP users were great and pool cleared up in no time and will not step back foot in the pool store unless I can't find something at Menards or Rural King.
Any ideas on how to get a very fine dirt out of the pool? The previous owner said they always had the stuff settle to bottom and easily vacuums up. So it has been happening for years which is why I think a lot of it is mill dust. I just don't have time to vacuum ever other day.

It's one thing for something nearby (i.e. mill dust, or pollen) to settle/sink in the water, but it's another to think it might be related to the filter's ability to sift it out. Because of your location, and suspect water source with what may appear to be metals in it, how about posting a full set of test results for us? Just so we compare levels to make sure we're not missing something chemically-related that may be contributing to your problem.
I'm not sure of your AGP set-up, but if you have any way to add additional return jets or angle them to improve circulation perhaps that might help. One of our favorite tricks is to drop a few ping pong balls or Styrofoam popcorn peanuts on the water to see how well they move towards the skimmer. That might help you confirm how well your water circulates.
