Hi everyone! I received my test kit today (Taylor Pro) and just finished testing my water for the first time with it. My readings are as follows:
Chlorine=.5
PH=8.2
FC=.05
CC= .05
Calcium=75
TA=300 (turned more pink than red at this point but didn't get any darker going up to 40 drops)
CYA=50

When I put the numbers in the Pool Math app it said to :

1) add 112 oz of chlorine ( I use liquid chlorine 10%)
2) add 56 oz of muriatic acid
3) add 1033 oz or 65 pounds of baking soda

I can understand doing number 1 & 2 but do I really need to add 65 pounds of baking soda? That seems like an awful lot to me. The only thing I have put in my pool since I set it up about three weeks ago was 4 pounds of stabilizer and maybe 10 gallons of chlorine total. I do have the 3" pucks in a floater that holds 3 at a time and I have only added 1 more since starting. This was a new pool just filled at the end of last month.
 
Yee Haw -- that be some baking soda. No. Do not add that.

Your FC number of 0.05 is not possible. Do that test again.

The TA test is likely not that high. See "Sometimes a static electric charge can build up on the R-0009 dropper bottle tip, causing the drops to be smaller than usual and making the test read higher than actual. You can prevent this by wiping the tip of the dropper bottle with a damp cloth or tissue before you start and after each drop."

Add the chlorine. See FC/CYA Levels

Check your input data. The app should not have suggested any baking soda.
 
Oh and your CYA is at a good number - pull those tabs out of the floater! You don't need it increasing further is you don't have a SWG.

I'm sorry that should be 0.5 as it barely turns yellow when I added the drops. I did wipe the bottle after each drop for the TA test but I will definitely retest both of these. Thank you!
 
Just went and retested but used the smart stir this time. All my numbers still came out the same. I have added the muriatic acid pool math suggested. How long should I wait before adding chlorine?

Huh...well now you know. (you did put the little x in the test and get it spinning....? :) ) 15-30 minutes should be fine.
