    How to lower chlorine level?

    Free chlorine is 12.5ppm- high level caused by operator error stenner pump feed of liquid chlorine last two days while I was away.... Pool is indoors and FL state max is 5ppm, so we are closed until i bring it back down. I have some Chlor Out by Haviland- Sodium thiosulfate

    Is there anything better?

    thanks,
    Mike

    There are a couple of different options, but sodium thiosulfate is what most people use.
