    Help with my numbers

    Hi everyone,
    I just want to make sure I'm on the right track.

    My water is slightly cloudy and there is a little debris on the bottom. When I scrub it disintegrates so I am thinking it is algae. The powdery stuff.

    I know I need to SLAM. I just got done scrubbing the whole pool.

    Should I bring up my TA first?

    PH: 7.3 or 7.4 (Most likely 7.3)
    FC: 3
    CC: 0
    TA: 50
    CYA: 40

    Not sure why my CC is 0. There is definitely powdery green stuff in the bottom. Not a lot but it is there.

    You may not need to bring it up at all. After your SLAM track your pH for a few weeks, if it jumps around, you might need to bump it up.

    Algae and CC can be had independently of each other ... there is a reason there are 3 criteria to stop the SLAM process.

    I would leave the TA, lower the pH a bit and SLAM away.

    Re: Help with my numbers

    Thanks Jblizzle and Mr. Bruce.

    Can I slam without reducing the PH?
    I have bleach but I don't have any muriatic acid on hand.

    I guess, I now understand why the 3 criteria for SLAM. I thought 0 CC meant no algae.
    Thanks for explaining.

    Ideally I would lower the pH a bit more, but it is likely fine to start the SLAM now.
