    I don't really see anything that jumps out. How are you chlorinating the pool? If you're using bleach your TA might be a little high but I wouldn't purposefully change it. It'll change as you adjust your pH and if you don't or rarely need to adjust that it's fine where it is.

    CYA is a little low. That's probably why you were burning through the chlorine. It acts sort of like sunscreen for chlorine.

    Pool Calculator says 37 oz would get you up to 40ppm. If it were me, I'd add 32 oz and leave some breathing room in case I wanted to use a few pucks later in the season while I'm out of town.

    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!

    yes using bleach, so far ph has been stable. I thought CYA was a little low and will bring it up to around 40
    thank you for the info
