    My numbers, what do they mean ?

    FC - 2.5
    CC - 0.5
    TC - 3.0
    T/A - 70
    CH - 30
    CYA - 50


    CL - 3 - using the block that came with TF 100 Kit
    pH - 7 - using the block that came with TF 100 Kit.

    Water Temp - 84 °F

    Water is crystal clear but is a bitksicky.

    Using BBB method with plenty of all the B's on hand.

    Hi

    Your PH is a little low, use some Borax to raise it. Do this first.

    Then, you can add chlorine, as that's too low too.

    Do you know how to use the Pool Calculator? Play with it, get to know it. It will help you figure out how much of each you need to add.

    Refer to the CYA chlorine chart - you need to keep your FC levels at the recommended levels for your CYA.
