Think I got mustard. It's light brownish looks like dirt or sand and poofs away like dust if you brush it. The pool has been covered with solar cover for past 5 days. Just showed up last night when I was doing my nightly check of pool. So I brushed all the brown and went up to extreme shock level. Ran filter.

7ppm drop!
I added another gal or 11ppm before I left and brushed again and filter running. Solar cover still on. Im going to check levels brush and vac when I get home and do a really good backwashing.
Im leaving for the weekend. Tomorrow at noon coming home sun at noon. Hopefully it won't go crazy while im gone. I was gonna get it up to 30ppm before I leave and run filter on 12hr cycle.
Im pretty good with checking levels I check Atleast once a day. I have noticed the increased demand 4-6ppm with the cover on. But thought my CC was just due to the cover. Guess I was wrong. I'll increase filter run time from 4hrs to 8. After I pass OFCL test. And I'll be buying a wall climbing auto vac. Hopefully that will prevent any issues in the future.
