    My algae has a little water

    Algae bloom in my Intex 30" x 12' above ground pool

    FC, after 60 drops, is above 30. The color never changed to clear.
    PH is above 8. Even after doing acid demand test ,10 drops, it never changed color.
    TA, after 40 drops, never changed to red.
    CYA black drop never disappeared.

    Can someone help me, please?

    Welcome to TFP!

    The PH test is not valid when FC is above 10 ppm.

    Add 30 ppm of CYA in a sock and SLAM. More here on how to add CYA and other chems, Pool School - Recommended Pool Chemicals

    Here is the process for killing algae, SLAM.
