Thread: Just how much is the calculator telling me to add?

    Just how much is the calculator telling me to add?

    For instance, for a 27,000 gallon pool, i put in my current total alkalinity (60) and my target number (120).
    the result was 4 oz. of baking soda.
    is that 4 oz. per 1000 gallons? or 4 oz. total?
    that seems like such a tiny amount.
    so if there's a formula for how much baking soda, calcium chloride, etc...i sure would appreciate it.

    many thanks,

    I get 380 oz of baking soda. Check that you entered all the numbers right. And as an aside...why do you want to go so high on TA?

    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!

    Welcome to TFP.

    Double check to make sure you have all your 0's in the gallons entered and ditto to the question Richard asked. Are you using trichlor as your primary chlorine source?
