A few weeks ago I started seeing these white snowflake formations on top of the water. I assumed they were from the dandelions blowing into the water. I've cut the grass and there havent been any dandelion shoots for about 10 days or so, but the flake formations are still on top of the water. Current weather is starting to warm up, and we have had several 80 degree days in a row. Anyone know what this stuff is? I have a sand filter, chlorinate with bleach, use Borax to adjust PH, and baking soda for the TA. Vinyl in ground pool. Pool gets full sun thru most of the day, most every day. I tried to post a pic below of the water surface.
FC 4-7 PPM depending on what time I added the bleach
CC was 0 last time I checked
PH 7.8
TA 70
CYA was in low 40s
I test with a Taylor 2006 kit.
