    Chem feedback please.

    Opened pool and chemistry is getting close I think. Looking for feedback on next steps especially for CH.

    FC = 6.5
    CC = 0.5
    TC = 7.0
    CH = 150
    TA = 50
    CYA = 60
    PH = 7.0

    If I used the pool math calculator correctly I think I should be adding the following:
    - 44oz of stabilizer to bring up CYA from 60 to 70
    - Lower IntelliChlor generator % a hair to bring FC down slightly (currently at 40%)
    - Add 150oz of baking soda to raise TA from 50 to 70
    - CH - pool math says add about 89lbs of calcium chloride to go from 150 to 450
    - For PH I was thinking since its close and tends to rise a bit on its own I would just let it be

    Should I be doing all the above at once or step by step and re-assess?

    Thanks in advance

    Raising your TA might help inch up your PH a tad. Everything else looks good.

    Rule of thumb here is to add things thirty minutes apart, except for CYA, because it takes a while to dissolve.

    I've never had to add any, but I have read here plenty of times that adding a bunch of Calcium can cause temporary cloudiness. So don't panic if it happens to you. Just leave the pump run and be patient.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!
