    just wondering

    why is the 1ppm loss ok for the over nite test, is that a margin of error for the tester , water is very clear cc 0 always less than .5

    I suspect that is because with no sun, there should be very little reason for FC to be expended other than some minor residual organic matter. If there is something actively "brewing" or growing in the water, then the FC will be consumed much faster, hence the 1 ppm rule.

    Having said that, I'm not the resident chemical expert. Let's see from other replies if I was close in my theory.

    There is always a little something falling in the pool that the FC will be breaking down.
    Also things like covers are broken down and consume some FC as well.

    Re: just wondering

    that makes sense, thanks. let me ask this, when my cya needs increased I use a couple of three inch pucks to bring it up, will the cya and fc for that matter get held up in the filter for a while, think I read for the stabilizer in a sock in the skimmer takes up to a week

    No the CYA and FC is immediately in the water when the trichlor or dichlor dissolve.

    The solid stabilizer is a different chemical makeup and take longer to fully dissolve into the water. Even when it is out of the sock, it may still not be fully dissolved into solution.
