    What order to add chemicals

    Here were my test results this evening:

    FC - 8.0
    CC - .5
    PH - 8.0
    TA - 90
    CH - 300
    CYA - 40
    CSI .40

    I need to add 37 oz Muratic Acid for the PH, which will lower my TA a little, so doing the Math i would need to add the backing soda 74oz baking soda after. Then would i raise the FC to shock level (15) for the first time? It is supposed to rain some on and off for the next few days, so should i just keep it the FC up around 7 until it stops or go ahead and start shocking?

    My plan was to add acid, wait, then soda and bleach right before bed tonight. Check the FC again in the morning adjusting back to shock level, home for lunch to check again, then once more in the evening to raise it overnight back to shock level, if needed. good idea?

    I don't see your PH level.

    You don't need to adjust the TA back up, that much acid shouldn't lower the TA that much.

    Sorry it was 8.5. It said it would lower TA by 6.4 so i changed it in the Calculator to 84.6 and it said to add 74 oz BS to get back to 100 or is 84.6 to 90 OK?

    You don't need to adjust the TA. 70-90 is the recommended range.

    ok thanks. I just saw that in the pool school. I was using the suggested levels on the calculator. Never again, as I have added the suggested levels from here to the top of my spreadsheet i use to track results.

    So i can just add the acid, wait an hour then add the bleach?

    You don't have to wait an hour. 15-20 minutes is fine.

    30 minutes should be plenty of time to wait for the acid to mix before adding the bleach.

    You're done SLAMing when:
    1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.

    Great. Any thoughts on the rain issue for my first ever
    BBB shock?

    How long do I wait after adding chlorine to test FC for overnight loss test?

    If you need to shock, go ahead. Don't worry about the rain.
