    Not really. You have some flexibility with TA as it relates to its effect on your pH which is really more important to us. If your pH remains stable in the mid 7s, then leave TA alone. But if your pH rises quickly, you would want to lower TA in stages to see if it helps keep the pH down better.

    Nope.

    If that's a brand new test kit, you might want to wipe the tip of the R-009 with a damp paper towel between drops. When new, that reagent can generate static electricity which makes smaller drops which makes things read higher than reality.

    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!

    Thanks for the explanation, Yes it is a new kit. I read that in the instructions but I didn't understand why they recommended that and I was lazy and didn't wan't to go get a paper towel . I will try it again correctly, when I get home.

    Re: Is this TA level too high

    My two cents added to the other post that are spot on. Don't get carried away with a TA number. With a vinyl liner you will not be having the same issues with say someone with a fresh plaster pool. Check and adjust your pH and not worry about TA. Once your pH is stable your TA will be in it's happy home. Mine likes to live at 60, my FIL's likes around 80, and the next door neighbor... well he uses a target number given by the chemical salesman "pool store". Now if you start using tabs or solid chlorine.... that's another story.

    Learn to take the advice here and be trouble free or use the pool store's advice. "You can't do both and get very far"

    Thanks for all the responses. I checked it again wiping the bottle tip and got a reading of 90.
