    Help with targets?

    Hey all. Posted a few days ago in another topic about getting my test kit and next steps...that convo came to a stand still, so I'm hoping to get some final help with my target levels to put into pool calculator when my FAS-DPD kit comes in and i'm ready to start the shock process. (green pool currently, sigh). I want to know which of the BBB chemicals to purchase and what to add to get all my chemistry in balance!


    So my levels the other day were (and I fully intend to retest once full kit is here)

    Currently at: (and I'm aware that we literally have no chlorine in the pool; we went away to NY for a week and came back knowing we'd start fresh, only have the dreaded tablets I've been told not to use, so we haven't added anything until we know for sure what to do for shocking process)
    FC: 0
    TC: 0
    pH: 7.4
    TA: 50
    CYA: 45
    CH: 110

    Based on my stats below, any help with what targets should be at? If CYA is 45, using the chart I found here on tfp I should be FC shock level of around 18 (between 16 and 20), correct? So I'm going to maintain at shock level until the three criteria are met (CC of .5 ppm, overnight loss test of 1.0 or less, clear pool)....anything else I have to do? I know my TA should also be higher, between 70-90+...so my real question is, with such a range, 70-90, what do I put in as my target for the pool calculator??

    Any help is sooooo appreciated!!

    I'd shoot for a TA of 70 to start with.

    Everything else looks good.

    Right now, all you need is plain, unscented liquid bleach without any thickeners...and lots of it. Job 1 is to get rid of the algae which involves SLAMing the pool (formerly called The Shock Process). As soon as your FAS-DPD kit arrives, you can begin this process. Once the pool is cleaned up, we can then focus on any water balancing adjustments that may be needed.

    A good test kit is an investment, not an expense.

    Just kill it.

    Everything else is easily fixed once the water's clear.

    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.

    Yay thanks everyone!! Ordered the FAS-DPD today and I already have the DPD kit from Leslie's for the rest; once those both run out/next season I'm definitely getting the TF100. Once that's here I'm ready to SLAM (love the new name ) this swamp!!
