    chlorine smell on skin - red eyes

    Pool was installed Mid-season 2013.
    First (partial) season, I stumbled through "pool store" maintenance.
    Then I found TFP, borated my pool and started the TFPC method, but using pool store testing combined with strips and and OTO/Phenol Red 2-way test kit.
    I haven't had any problems. After swimming, I've always felt as clean as having just showered.

    Salt water pool, as per my signature, but I usually open with liquid (10% pool chlorine from hardware store, verifiable by predicted FC increase)
    After a pool party, or even just a significant number of swimmers, I measure FC and then boost to 4ppm or so with liquid, rather than use the slow "superchlorinate" mode on the SWCG.

    So I opened the pool about a month ago, once the ice was gone, adjusted up the borates and salt, and balance the pH and such, and and have been dosing with liquid chlorine before turning on the heater to get the water out of the 50s F so the cell is more effective.
    The weather has warmed up and we fired up the heater this past week.

    Yesterday afternoon, I took a full set of readings with my TF100 purchased new in Oct 2015.
    Pool is heated to 84F
    FC - 4
    CC - 0 ( Completely 0. Previous test when I opened the pool a month ago was 0.5, so I held at ~10PM for several days with negligible CYA)
    pH - 7.6
    TA - 50
    Cal - 150
    Borates - 60
    CYA - 50
    Salt - 1500 (Hayward Aqua Rite Low Salt system. T-CELL-LS requires 1200-1800 PPM salt)
    (I've also double checked the FC/pH/TA/Hardness with a 4-way dip strip that seems to agree with the TF100 readings)

    Everything is pretty much the same as it has always been.

    From a SLAM standpoint,
    The water is brilliantly clear
    Overnight chlorine loss is negligible. I dosed to 10PPM early last week and still had 3.5PPM on Wednesday so 6.5PPM drop over 5-6 days.
    CC is 0

    We just started swimming the last two evenings and the water feels great, while in the pool.
    That said, I swim underwater with my eyes open a lot. Shortly after getting out of the pool, my eyes look like ripe cherries.
    And my skin reeks of chlorine.
    This has never been an issue in previous years.
    I showered after swimming last evening, with a strongly scented shower gel (Lever 2000 Sport, something something) and an hour after showering, I could still smell the chlorine on my hands and arms.
    A few drops of visine cleared up my eyes after a couple hours.

    But I'm at a loss as to why this is happening now?

    The only thing any different this year is that I've left my TA lower, and didn't up my calcium.

    Last year I had to add about a liter or so of muriatic acid every couple weeks while the TA was adjusted to around 70, but my subsequent research has lead me to believe a lower TA (closer to 50) will help me get in the groove and keep the pH in check.

    Also last year, I upped the Calcium to 200-250 after the post winter top-up, but didn't this year because everything I read on here says it isn't important for a vinyl liner pool.

    Help?

    Did you use RV anti-freeze to winterize your pool?

    Re: chlorine smell on skin - red eyes

    Hmmm. Either last year or the year before (I'm really thinking it was the year before, but I can't be sure), I poured some around the Gizzmo and some in the pump housing. maybe 1/2 gallon total.
    Could that cause either the skin smell, the red eyes, or both? In such a low concentration? Will it go away / break down?

    Re: chlorine smell on skin - red eyes

    RV antifreeze is nontoxic BUT when used in swimming pools it will break down from chlorine oxidation. One of the by-products is the formation of chloroform. Chloroform is an eye irritant and would have a funky/weird chlorine-like smell to it. It does breakdown slowly and it should all go away. However, if it was two years ago, it would all be gone by now.

    You might want to SLAM your pool to see if any CCs form.

    Interesting. Thanks.
    Yeah. The pool was held at shock level for a week (>10PPM FC with <20PPM CYA) when I opened it. Knocked off the 0.5 PPM CC I measured at the time.
    Since that has long since passed, and I'm currently passing the 3 requirements for SLAM, should or could it be an issue now?
    Or are you suggesting to increase FC to SLAM/Shock level and see if CCs appear?

    Yes. Just raise your FC up and see if anything forms. Shouldn't take too much bleach to do that.

    Raised the FC to about 12 overnight. No CCs appear to have formed, (maybe they formed and then oxidized out over night) but I'm no longer experiencing the smelly skin or red eyes.

    Re: chlorine smell on skin - red eyes

    You should perform an overnight chlorine loss test (OCLT). The directions are in Pool School. At least I would do that.

    Re: chlorine smell on skin - red eyes

    I did one prior to this, but I'll do another for interest's sake.

    Ok. It sounds like whatever was bothering you finally burned off. OCLT is just to make sure your water is good. I'm sure you'll be good to go.

    Re: chlorine smell on skin - red eyes

    The chlorine smell on your skin is the result of the chlorine oxidizing dead skin and other stuff on you. Some people report that a vitamin C lotion or crystals gets rid of it. It might help to shower before entering the pool so there is less stuff there for the chlorine to work on.

    But you may want to be aware that some serious medical issues can cause your skin to have a similar smell.

    Re: chlorine smell on skin - red eyes

    OCLT is good, and no CCs showing up on the test.

    Haven't had any red eyes, or skin smell since those first two days after we opened the pool, so I'm gonna just assume it may have been residual antifreeze, or something that the chlorine burned off.

    Thanks for the advice.
