    CYA is high

    Hello,

    Somehow my CYA is sky high. Does adding baking soda impact CYA levels? Also, my pH is high. Can I lower my pH by adding muriatic acid without further increasing CYA?

    Please take a look at these to get this straightened out ...
    ABCs of Water Chemistry
    Recommended Pool Chemicals

    Baking soda only raises TA a significant amount
    Muriatic acid lowers pH and TA

    Neither have anything to do with CYA.

    How are you chlorinating your pool?

    Please post a full set of test results and tell us the kit you are using.

    Re: CYA is high

    Thanks for the info. I'm guessing that my CYA has jumped up due to initially using pucks and haphazardly adding stabilizer. My current readings are: TC=1, CYA=180, Alkalinity=180, pH=8.2

    Pool store told me to broadcast 8 cups of baking soda once per week to "prolong the life of my liner". Is there any truth to this or any benefit to regularly adding baking soda irrespective of alkalinity levels?

    Yes, but to Jason's question, how are you testing?

    Your pool store is full of it. Only when you decide to do your own testing will you be able to manage your pool. Stay out of the pool store.....honest.

    NO! there is no reason to randomly throw baking soda into the pool to protect your liner. Only add what your test results indicate needs to be adjusted.

    I'm using 6-way test strips from walmart. I know I need to purchase a proper testing kit. It's on the list...

    Well, until you do so, there is really no way to offer balancing advice.
