    Safe time to wait between LC and CYA

    After putting in LC, how long should I wait before putting in Liquid Stabilizer to increase CYA?

    Here are my numbers (I use TFT100 testkits):

    CYA can be added at the same time. See instructions on how to add on this page: Pool School - ABCs of Pool Water Chemistry

    Thanks JVTrain.
    (I am using the Liquid form, so no need for extra steps - just pour, I suppose)

    I also noticed that you were targeting 30 ppm from 20 ppm in your Pool Math. Unless you're planning on using pucks later in the summer or off and on throughout the summer, I'd suggest going to at least 40 ppm CYA if not 50-60. You'll consume less chlorine that way based on your location. But you might just be working your way up to that slowly.

    Yes, you are correct, I intend to use 4 - 3" Trichlor Tabs about (32 0z) that should raise another ~10 ppm when on vacation. Moreover, I have an opaque automatic pool cover that is closed most of the time (~95% in non season to 80% season), so that will most likely lessen the chlorine usage by some. -Thanks.
