    0 FC drop is this normal?

    I haven't had to add any bleach to my pool now for 2 days is this normal?

    6/11

    FC 3
    CC 2
    CYA 40
    added 60 oz. of 8.25% bleach to bring me slightly above my target (trying to learn my demand and paranoid)

    6/12 full test day
    PH 7.5
    FC 7
    CC 1
    CYA 40
    CH 150

    6/13
    FC 6.5
    CC 1

    6/14
    FC 6.5
    CC .5

    Zero bather load since adding bleach pool docent see the sun until maybe 11 ish then has it the remainder of the day.

    Is this a normal thing? Just curious not really concerned anything is wrong. Trying to figure out this pools habits is all.

    Thanks

    Yeah, it is coming down but really slow. Be Thankful.

    As an aside, your cc's are OK today but thewy were too high in days past.

    If your cc's consistently stay above .5 ppm, I would suggest you SLAM your pool.

    I thinks it because we have had some overcast days here and rain. I am learning my pool and couldn't be happier. I have noticed this in the past but passed an OCLT so figure I would be fine. Thanks for the nod that it can be normal under certain conditions.
