Thread: Shocking a newly re-plastered pool

    Shocking a newly re-plastered pool

    I added chemicals to my newly re-plastered and freshly filled pool.
    Water is sparkly blue.
    all numbers are good,
    TA - 80
    CH - 400
    Ph - 7.2
    except the FC went from 0 to 12 with one application of chlorine.
    I have a 6600 gallon pool and added 2 gals of chlorine. This seemed like a reasonable amount
    but this morning the FC read 12 !!
    The CA is barely registering, but i am hesitant to add any to the 1 lb in sock in the skimmer.
    I removed the trichlor pucks from the in line feeder.
    I was told NOT to shock the pool during the first two weeks of curing, and truly did not intend to.
    I am hoping that by not adding any more stabilizer the chlorine will burn down to acceptable levels.
    I wonder though...did i do any harm to the new finish by adding so much chlorine? If so, what can i do
    to correct the situation.
    thanks

    With very little CYA, that number should drop quite quickly in the sunlight. I wouldn't worry about it.
