    New Plaster start-up

    New plaster start up. Filled the pool today and added the Jack's Magic Magenta. Just busted out my new TF-100 test kit along with the Speed Stir. Recorded the results and punched them into the pool math. First timer so hoping I got it right.

    FC - 2.5
    CC - 1
    TC - 3.5
    PH - 7.5
    TA - 240
    CH - 250
    CYA - 0

    Pool Math has given me several directions - bleach, acid, calcium chloride, and stabilizer. Being's this is a new plaster start-up I think I should start with the acid...(58 oz. of 38.45%). Going to wait until daybreak to add the acid. Hoping someone can weigh in on this before then!

    Numbers look good to me. TA is high and will push PH up. All I would add is cya right now.

    Re: New Plaster start-up

    So just go with the stabilizer now and no acid?

    No acid yet. Just need to manage pH right now. We can work on TA later.

    Re: New Plaster start-up

    What kind of stabilizer do you recommend? (And thanks for the input!)

    You're welcome. Any granular is fine, 99% cyanuric acid. I buy mine at Lowes. Put it in a sock or knee high. More here, Pool School - Recommended Pool Chemicals

    Re: New Plaster start-up

    Ok...I did another test this morning with better light conditions than last nights test. Numbers changed a bit.

    FC - 0.5
    CC - 0.5
    TC - 1
    (When I tested with the K-1000 it looks there isn't any chlorine at all.)
    PH - 7.6
    TA - 240
    CH - 250
    CYA - 0 (I filled the test tube all the way to the top and could still see the black dot.)

    Heading out to the pool store now to get some stabilizer. Pool Math says to add 107 by weight or 111 by volume. I'm guessing more people add by volume with a measuring cup?

    Also...when should I add chlorine and start worrying about PH and TA (new plaster).

    Re: New Plaster start-up

    Ph is right where NPT wants it. PH is most important, it should be managed as often as needed to keep it in range. Once or twice daily. FC needs to be maintained ed daily also, above minimum for your CYA, FC/CYA Chart. You don't want to get algae and have to SLAM new plaster. Yes, a measuring cup is good for CYA.

    Re: New Plaster start-up

    So should I add chlorine before stabilizer, during, or after?

    Re: New Plaster start-up

    Any of the above is fine. Soon is the operative word.
