Taylor Kit users or Math majors help.

[96SC]

Using the Taylor booklet, table A, to introduce 1 ppm chlorine.  If I have a 400 gallon spa and want to add 1ppm with 56% chlorine, how much would I use?  The booklet gives results for 45% and 60 % chlorine.  To the best of my 'sypherin' I come up with .1 oz.  Does that sound right?  (Math majors, here are the amounts given:  45%= .12 oz and 60%=.09).

The container label is no help either.

Thanks. :-/

Don't over-think it lol.  I add bout 1.5-2 ounces of di-chlor,AFTER I'm done using spa.  That typically lasts in regards to sanitation....3-4 days.

Since you are using 2 items you must add them together  and divide by 2 to get the average.

(45+60)/2 = 105/2 = 52.5 SO (.12 + .09)/2 = .105 ... so the answer is NO it is not 1 oz! 1 oz is going to give you 1 PPM if the chlorine was 52.5 %   Try again!!!     Now to add to your misery, each teaspoon is 0.16 oz so you need to know how much chlorine does a teaspoon give you.  8-)








**Just kidding**  ... I did the calculations a while ago and you need 0.096 oz of 56% dichlor to give you 1 PPM chlorine.

To make it even easier for you, I have a 400 gallon tub and I use 2 heaping teaspoons to get about 3 PPM +/- something. The only difference I use chlorine from Doc that has 62% active ingredients and the amount needed to get 1 PPM is 0.087 oz.

.1 oz. vs. .096 oz.  Close enough for government work. [smiley=thumbsup.gif]

Thanks for the input guys.

gallons of water in tub x desired ppm x .000128 / % of available chlorine in dichlor = amount of dichlor to add in ounces.

Example -  400 x 1 x .000128 / 56%(.56) = .091 ounces

3 tsp per TBS
2 TBS per Ounce
