    Question High PH but low CYA

    I just tested my pool and everything else seems to be in tack but the PH being high at 9 and my CYA is 0....I know to lower PH is to add muriatic acid but i'm confused on the CYA.... ie. is it normal for it to be low when the PH is high?

    They have nothing to do with each other. Have you added any stabilizer? Is it a new fill? Then it will be zero.

    How did you measure pH that high?

    They are independent of each other, but when you add CYA it lowers PH.
