    STRONG CHLORINE SMELL AND BURNING EYES

    I have a new pool x4 weeks and now have a strong chlorine smell and water that burns your eyes.

    pH 7.4
    TC 5
    FC 5
    CC 0
    Alkalinity 80
    Calcium 450
    CYA 45

    How do I get rid of the smell? Also, I have a lot of white buildup that i can remove with Muriatic acid (I can also remove the grout with this too-unfortunately).

    Thanks for the help.
    p.s. For chlorine I use liquid bleach, and triclor tablets.

    Re: STRONG CHLORINE SMELL AND BURNING EYES

    The "chlorine" smell and eye irritation is caused by CC. My guess is that you are using a DPD chlorine test, that tops out at a reading of 5. That means that your actual levels could be higher and the CC level might not actually be zero, as your test appears to indicate. I suggest diluting the pool water one to one with some chlorine free water, like distilled water. Then do the test again and multiply the results by two. Better yet, get a FAS-DPD chlorine test, so you can directly measure the CC level.

    Your CH level is rather high. If you don't live in an arid climate, you should replace some water to lower the CH level. In an arid climate, you need to expect high CH levels and practice ways to deal with it. I can explain that more if you are indeed in an arid climate.

    I live in league city texas, by houston. i use the DPD chlorine test in the kit by Taylor. How much water should I dupm and replace to get CH lower?

    I don't have any distilled water today, but can get some for tomorrow. In the meantime, should I shock the pool?
    thanks

    Shocking is good.

    How much water to replace depends on your fill water CH level. If your fill water CH level is low, then you need to replace 25% to 40% of your water.

    New plaster is going to have water balance issues. For a new build your CH is not really THAT high but you need to keep on top of the ph to make sure it does not rise above 7.6 and you need to keep brushing the pool several times a day if possible but at least once a day until your plaster settles down. This could take a few months.

    Thanks.

    I have to admit, for the past week or so, I haven't been brushing the pool. Also, if i miss a couple days ckecking the pH, it will shoot up.

    Does the new plaster release calcium?

    Re: STRONG CHLORINE SMELL AND BURNING EYES

    FYI, my fill CH level is 110ppm.

    Unless I hear otherwise, I will drain 25% and refill.

    New plaster releases calcium AND causes the pH to rise. I would wait to drain but do keep on top of your water balance and keep brushing for the present! It WILL settle down soon.
