Every morning when I brush the flooor of my pool, I get a fine powdery mist that quickly dissipates. It is much more prevalent in the deep end of the pool, which is more shaded in late afternoon, although I will get some powdery mist in the shallow end as well. However, the powder does not seem to result in any cloudiness. I try to brush it toward my floor drain, but I seem to have it every morning.
I thought this could be dead algae, but I wasn't sure. It seems to be there even on mornings the day after I vacuum.
The only chemicals I have been adding to my pool over the past two weeks are chlorx bleach. Before that, I had added calcium hypo and soda ash. But I haven't added either of those since June.
