History, had this in April, a month ago, and showed up again two days ago. Slammed both times. They are building a new house behind me and the first time it started had cleared the lot and removed many many trees. Last Thursday and Friday they brought in that nice red dirt and did the final grade. I want to think it's dirt etc., but could be algae. It shows in the same areas (dead spots?) along the top edge of slope. The water was a little hazy Friday, clear yesterday until I brushed. Water has never been green, but is naturally a turquoise hue. My FC has never been below 6 except the very first time it was 4.

I did the OCLT last night zero loss. I have never had any FC loss with this stuff. CC always zero.
I did lower the Ph a little yesterday and bumped the SWG up. Brought it up from 8.
Tried to attach a photo but says it exceeds ??
This stuff collects around the edge slope in a few spots and a little on steps. Looks slightly green yellow. It does collect on the bottom also in varied amounts, but isn't visible until I brush. Mostly brown dust when I brushed yesterday. Haven't brushed yet today.
My only conclusion if not dirt mustard algae.
Of course I have company coming Saturday and don't want to SLAM right now, especially to mustard level. My FC takes forever to drop.
Any opinions. I'll try to get a photo on here.
