    First test this year

    I did a test and found my ph at 7.2 and the TA is 100 with the cya at 30. Should I get the cya up first to 80 and then work on the ph or the other way around. It is going to be awhile before we can swim because the weather here in NW Wi. can't even get to 70 and I don't have the heater hooked up yet so I have time to get the levels perfected.

    The high TA will make the pH drift upwards. Keeping pH in check after the rise will take care of TA. Basically, I would just monitor them both, but as of now don't worry about proactively changing them.

    I will just monitor the ph and TA but will get the cya up.

    Target 70 when you add CYA. If you come up a little short, it's easy to add more, but to lower it you'd need to drain and would lose salt, too.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!
