Thanks again. I have noticed that I am still getting piles deposited overnight in the center of the pool. What I want make sure of is whether it's algae or just the coagulated reminants from the floc treatment.

I have vacuumed to waste twice and been running the robot a lot. It's a brownish color just like what accumulated when I added the flocculant.

My water temp is a cool 74.
My PH was 7.4
FC was 12ppm
ALK was 90

Should I be concerned about algae or does it take this long for the particles to slowly stop precipitating?? Otherwise the water is clear.
