    Question safe to swim?

    Just added CYA (via sock in skimmer method 3PM yesterday). I squeezed it every few hours to get it to dissolve faster and it was pretty much gone by this morning. I've since removed the sock and the pump is still running. I noticed the surface is covered in little white flakes, which I assume to be undissolved CYA. Is it safe to swim with those flakes still floating around? Not sure why they are not getting lodged in the cartridge filter, which I cleaned just before adding the CYA yesterday? It seems as if the flakes are just getting pumped through and back out through the jets.

    All other chemicals are in balance and have been for months:
    pH - 7.5
    Chlorine - 4.0
    CYA - 25 (before adding new stuff yesterday)
    TA - 80
    Calcium - 250

    From other threads I've seen maybe it isn't CYA, some sort of calcium being produced? Or maybe windblown material? I did check around and it seems as if some other surfaces have some white flakes so maybe it is windblown. I also included a picture below. I just don't see how it could be CYA as this stuff must be getting caught in the filter... then windblown more of it so filter/pump can't keep up?

    Did squeezing it affect your hands? I'd go swimming.

    You could actually go swimming with the CYA granules still in the basket, so it's safe since it's dissolved.

    So ultimately not sure if it was actually CYA or windblown stuff, but we went swimming and later that day/evening it seemed to be gone.

    Got a feeling you might have a hole in the sock to have granules in the skimmer basket. When you squeeze the stock you might get a white cloud, but not granules. That they disappeared probably means they completely dissolved. (Thats a good thing)
