    New Pool Water & Need to Adjust

    I finally got my TF-100 test kit after I had the pool filled last week with treated water. Without knowing where my levels are to start I added some HTH Conditioner to get my CYA levels up & have been adding HTH pure chlorine liquid daily (obviously too much as the test results show below) I have a Intex SWG that I will be installing but wanted to test my levels first. My FC is through the roof & have no idea where to begin so any help is appreciated, thanks.
    FC- 23
    CC- 0
    CH- 125
    TA- 220
    CYA- 30

    Nothing to do at this point besides stop adding chlorine and let it drop.
    How much were you adding every day? Clearly more than the 2-3ppm that you should have been adding
    Were you using PoolMath?

    You can add the salt and let that get well circulated while you wait.
    You will also want to raise the CYA more when you are ready for the SWG to take over.

    Also, please add your pool details to your signature as described HERE as it will help us help you.

    I'm sorry, I added my signature after I posted & figured it would update. I added 16 ounces per day based on pool math incorrectly.

    Well, then something does not add up. 16 oz of 10% bleach should have only added about 2ppm ... if that was done for a week, you would have only added 14ppm of FC not including the losses that definitely would have happened to the sun.

    So, now I suspect test error, unless you added something else to the pool.

    Can you describe how you did the FAS-DPD chlorine test? Using 10ml of water right? Did you actually count 46 drops?

    We've had minimal sun, the cover was on over the weekend for a storm & today is the first day with full sun. I did add 46 drops but will retest to confirm, hopefully it was error.

    10ml of water or 25ml of water?

    10ml with a heaping scoop from the blue scooper included in the kit.

    Did the sample start with a deep pink color after the scoop? FYI, you can not use too much powder, but too low can give questionable results. One scoop is fine for normal FC levels, but a little extra at higher FC levels will not hurt.

    Yes, everything looked right according to the instructions. I think the problem may be that I started with "treated pool water" according to the delivery driver. I have a well here so I had to pay for a company to deliver pool water. The website lists it as treated but no mention how or with what.

    Interesting, maybe they bump the FC level up pretty good before delivery to make sure nothing starts growing in the water.
