I am new to the TFP methods. I am trying to get my CYA to around 50-60 so I can start the SLAM. I have been draining and filling for past week, and testing using my Taylor K-2006. I wasn't sure if I was reading the test correctly because it was still showing like 75, so I ran up to the pool store and they said it was 58. All other tests are within the recommended ranges. So last night, I decided to add 64oz Clorox Germicidal Bleach which is 8.3%, to see if it would raise chlorine level at all. I just tested (18 hrs after bleach add), and after putting in the 2 scoops of the dpd powder, the water did not even turn pink, which I guess indicates there is no chlorine?
So my first question is, if the water doesn't turn pink, does that mean there is no chlorine, or no free chlorine? I am confused since I cannot do part 2 of the test, if there is no pink to turn clear.
Second, the pool calculator suggested 121 oz of 8.3% bleach to raise 27k gal pool from 0 to 3, and I only put in about half, so I assumed I would at least raise it to like 1.5, but it is still 0. I just tested CYA again, and according to my readings, I am still at about 75. Is that high enough to allow all that bleach to get "eaten up" by the sun in one day?
My other tests are:
Calcium Hard: 100 (vinyl liner)
Alkalinity: 70 (I put about 7 lbs baking soda in 4 hrs before bleach, but haven't tested since)
