    New Pool Questions

    Going on week 3 with water in the new pool. Chlorine seems to drop overnight, from 3ppm to 1.5ppm, is this a normal drop? Also bought bleach at Home Depot, it's their brand, Germicidal Bleach, but I can't tell if its 8.25% or 10% strength. Using pool math, if it's 8.25%, it suggest to add 32 oz to bring my FC level up to 3ppm. My test results are:

    FC 1.5ppm
    CC Less than .5ppm
    PH 7.4
    TA 225
    CH 70
    CYA 40

    I am making progess with lowering the TA, 2 days ago I was at 260. My PH shoots up over 8 after a couple of days, so I am having to use alot of acid to keep it normal. Is this standard with a new pool?

    June 2016, 32x16 IG, approx 16k gallons, Plaster, DE, Jandy dev60 filter, Jandy 2 speed pump and Taylor K2006 test kit.

    That means you have something in your water consuming your chlorine. You need to SLAM it.

    Print this out and leave it with your test kit Pool School - Chlorine / CYA Chart Your FC is too low for your CYA inviting problems.

    Yes, new plaster raises pH drastically, and it will continue to for ~ 1 year.
