    CYA question

    So I have a 28K pool and every year I add 1/3 new water to my pool to get my CYA down to 30. This year they checked it and said its zero. I asked how that's possible and they said it dissipates over time. Is that true?

    Re: CYA question

    Last year I lost all my cya and the water never turned green. (turning green can create a condition where the cya is converted to ammonia then neutralizes, but sometimes the ammonia doesn't convert but thats a whole other topic) It rained a ton though and I must have drained a few
    feet of water.

    but ya, it can happen.

    This winter I didn't lose any and it still rained plenty...go figure.

    You should really confirm whether you have ammonia prior to adding any CYA ... otherwise you may make the ammonia problem worse.

    Who is "they"? Are you not testing your own water?

    Re: CYA question

    I actually went to Leslies which I never do, only because my wife put my test kit up for winter I can not locate it. Go figure. Also this year I had a lot of white powdery stuff that settled to the bottom 3 days after I opened it. I have nver had that happen, it covered the entire pool bottom.
