I am still learning the TFP method, although I think I am getting there. I have my TF-100 kit and speed stir, and I have tested my water twice so far, these are my numbers.
May 9, 2017
CYA - not tested, will test later (still adding conditioner at this time)
FC - 3.5 - 4 (I accidentally dropped two drops at once, so I don't know if it would have taken 7 or 8 drops)
CC - 0
TC - 3.5 - 4.0
TA - 30
PH - 6.8
Temp - 70 degree
Yesterday, per Pool Math, I added 114oz of bleach (to raise FC from 4 to 7) and 11 pounds (to raise TA from 30 to 60) of baking soda
These are my numbers today....

CYA - 45
FC - 4.5
CC - 1
TC - 5.5
TA - 90
CH - 200
Bor - 10
PH - 7.5
I think everything looks ok except maybe the FC, which should be higher. I don't understand about the other numbers.....even though I followed PoolMath exactly, I overshot the TA by 30 points. It does seem like the baking soda also raised the PH some, and I think the CYA is ok. So should I shoot for a FC of 6? Yesterday I used 14 cups of bleach to raise the FC by .5. Today PoolMath is calling for much less bleach to raise it from 4.5-6, when yesterday the amount that was supposed to raise it by 3 only raised it by .5. Should I continue to follow the PoolMath recommendations a few more days and see if my FC levels rise? Also, I have not intentionally added borates to my pool, so where do those come from? Thank you in advance
