    Please redirect me if this is in the wrong area. I was wondering what I would be better off using for chlorine. I have a NG heater and in ground copper supply/return lines and would like to stretch out their lives for obvious reasons.

    Thanks for your input.
    My pool is a circa 1980 18 x 36 Kidney shaped plaster IG, sand filter, approx. 20,000 gal. w/ in-line gas 125,000 BTU heater.

    Welcome to the forum!!

    The type of Chlorine does not matter as far as metallurgy is concerned. Once diluted, and distributed in the water, all forms are all identical. It's the amount you have in proportion to your Cya level that matters most. Also, keeping proper control of pH is even more critical if you are concerned with preserving the Copper piping. If you don't have one, I cannot recommend strongly enough that you get a very good test kit and start using it ASAP.

    For metals, I believe pH is the important factor. A low pH is bad for metal pipes and such. Along with maybe CH because of scaling

    Here's a good argument against acidic trichlor pucks and for getting a test kit and using it often.

    Maintain your chemicals correctly

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!
