I had previously posted about having clouds of "dust" when I brushed at night. After two weeks after cleaning filter and brushing 2-3 times per day and running pump more often than usual (before was like 2-3 hours 2500rpm and maybe 4 at 1000-1750 rpm, added 3 hours or more per night at various speeds) the plumes of dust are largely gone when brushing. But I still have light colored, almost transparent floaties that I can even see during the day when sun is less intense. Thin slivers, less than the size of a broken in half grain of rice. Almost look like broken insect wings. Other than a few light brown flakes, most likely leaf fragments based on what ends up in the skimmer and filter basket, there is no other colors. No black, no yellow, no green. Filter pressure steady, shows no increase since cleaning ( I have overly large 425 sq ft filter for a 10-12,000 gal pool)
Water is clear, not cloudy, just those particles. Never have had algae. Not before TFP, not since bleach only a year ago.
With CH of around 520 I am following the advice here to keep CSI at lower range to prevent scale. CSI with my current numbers is -.37
Numbers last night around 8:30 PM
TA 60
PH 7.2
FC 11
CC 0-.5 ( 5 drops R3 makes the solution a little cloudy, barely a tinge of light pink, one drop of R71 brings it back to normal.
Added a lot of bleach last night to see if I had any overnight loss, measured and got 18 FC
10:00 AM numbers
TA 60
PH 7.2 (seems to read the same as last night in spite of high FC)
FC 16
CC 0-.5
Since sun has been on pool since 5:30 AM I don't think a loss of 2 indicates an issue.
Tried to take some pictures but it does not show the particles, too small, too transparent.

What does calcium look like when if/when it precipitates out? Is that a possible explanation? Previously my TA was 100-120 and PH 7.5
Do not know if I have a problem or just being overly anal
