    Lowering chlorine

    Could i lower my chlorine by adding ammonia to the pool. Was slaming the pool and guess my son overshot the chlorine by alot yesterday. Its over 50 ppm (stopped at 100 drops it was still pinkish) We have a big gathering tomorrow and was planned on the pool being ready. Its clear with a slight cloudiness in the deep end. I have over 40 gallons of 12% chlorine to fight if it kills too much.

    I do not understand your last sentence.

    What is your CYA?
    You can use hydrogen peroxide to lower the FC.

    Do you know what your cya is. I read in another thread about using hydrogen peroxide to reduce it. Check into that.

    It will lower FC at the same rate that bleach raises FC. Enter your target FC in Now and what you want it to be in Now. Choose 8.25% bleach and that amount of HP will lower FC that amount.

    Re: Lowering chlorine

    Is it that amount in gallons correct? Guess I'm just getting desperate so was thinking of using ammonia

    Yes. You can buy HP by the gallon at the drug store.

    Re: Lowering chlorine

    Using ammonia to lower FC shortly before a gathering is a terrible idea. It will create a large CC situation that will make your water very uncomfortable. Strong chlorine smell, burning eyes, the stereotypical chlorine pool symptoms.

    Use peroxide or a store bought chlorine neutralizer, not ammonia.

    Ok thanks for all the help everyone. I "knew" it wasn't a smart idea but very desperate. Thanks again

    No one locally had anything to reduce chlorine as far as pool store related chemicals

    I hope this is not too late for the party but ahem, pool stores that sell baquacil stuff have HP and they call it shock. Hope that helps.

    Add your country or state to your location in your profile, I thought all drug stores sold hydrogen peroxide.

    Re: Lowering chlorine

    Just wanted to say Thank You to everyone. The peroxide worked great needed alot less than i thought. I think my son might have measured wrong. After adding some it went down to 10ppm. Everything was great. Thanks again
