    Water wasn't as dirty as I thought it was but numbers are off.

    Free/CC - 0 ppm
    Water pH - 7.0
    Total Alkalinity - 20 ppm
    CYA - 0 ppm

    Should I first add some baking soda to get my pH up some? I could have sworn I seen an excel sheet somewhere here that told me an estimate of how much I thought.

    Also, what about Alkalinity? I've never seen it this low before.

    Start with a box of baking soda. It will also raise that low TA. Also add about 2 gallons of your bleach. You want to aim for about 10ppm for shock level, but who knows what strength is left. You can retest FC/CC after it circulates.
