Here is a 6 second video that shows a cloud of dark green/brown that lifts up when I brush some surfaces.
I don't know how to embed it here, so imgr link.
Is this algae build up, or is something else? Water is clear and I've never had an algae breakout.
This is a screened in pool area that doesn't get a lot of direct sunshine because there are tall pines and other trees on one side. It faces west. So maybe 3-4 hours of direct sun at most.
CYA between 60-70, FC around 4.5, TA is 80, PH around 7.4-7.6. Ch around 250. Water temps around 84 these days.
Pine straw hangs from the screen all the time, they decompose and fall into the pool.
