    Question about adding bleach

    There have been a few times recently that when I add bleach, it seems to bubble up to the top of the water and float around the pool. Usually when I pour it in, it goes straight down and is pushed away by the returns and never bubbles up.

    Could this be a sign of bad bleach? The only reason I ask is last time it did this, I had an unusual amount of FC loss. I have checked for OCLT and pass with flying colors so it is not that.

    Thanks.

    I know when you bring a pool up to shock level when organics are present, you will see bubbling pretty often. Can you post a full set of test results? Do you have CC present?

    You're not using one of the speciality bleaches are you?

    Bleach is heavier than water and I have never seen it float or bubble up.

    Just regular bleach. I can post a full set of results later. I very rarely have any CC, if I do it is only .5 or less.

    FC: 2.5
    CC: .5
    TC: 3.0
    pH: 7.8
    CH: 300
    TA: 120-130
    CYA: 30

    I am adding a lot of acid every 3 days or so to keep pH down, but the TA does not seem to really be dropping. Is that because I am not being as agressive with dropping it since I am only adding acid every 3 days or so? I remember when I had it at 90 pH would hold for like 2-3 weeks.

    Thanks.

    Re: Question about adding bleach

    Also I just noticed this morning that some of the tiles have fallen off of the side. Is there a way to put there back on?
