    New liner, how get started?

    I had a new liner installed. The pool is filling with well water and I anticipate it being full tomorrow. The company/crew that installed the liner said to add some "flock" to remove the iron. I went to the pool store and bought a 24 lb box of chlorine, but they had never heard of flock. I believe my pool is 18,000- 20,000 gallons. What should I add to the water tomorrow?

    What kind of chlorine did you buy? Are you intending to use it to raise the CYA as well.

    Flock has nothing to do with metal in the water.

    There are articles in pool school to get a pool started (Temporary Pool Guide) and dealing with metal (Metals in the Water and Metal Stains)

    Have you had your water tested? A lot of places require wells to be assayed and if your locality does, you can get the report and it'll tell you what's in your fill water.

    The first thing you should add to the water is some FC then test and adjust the pH if needed.
    Then if your water does have metals you'll need to add some sequestrant.
    After that you'll need some CYA in the water. I'd add enough to get to about 30 ppm.

    I have Calcium Hypo, and I just put in 5 lbs...I am recirculating the water through the sand filter...

    I'm planning on testing the water later today with my TF-100...

    Thanks for the input!

    Cal hypo adds calcium not CYA. You need to get some stabilizer in the pool or the sun will consume your FC very quickly.
