My CYA is not showing up. The pool store said it was 34 on June 15th. They told me to add another 4 lbs of stabilizer. I had added 4 lbs a week prior so 8 lbs total. I used the stocking method. The last of it dissolved two days ago. I shook the solution for over 30 seconds and had my back to the sun when reading the result. The black dot never went away when facing the sun or with my back to the sun. This is a new pool. 28,800 gallon above ground, 54" height 33' round. I use liquid bleach. My test today using the tf-100 is chlorine 3.5, 0 cc, 140 TA, ph 7.5. I will wait a few days and test the CYA again. The water looks crystal clear.
The pool store gave us an ionizer in the pool package but we returned it. They are pushing trichlor pucks and told us if we use liquid chlorine we will have to shock every week.
Does anyone have suggestions for the CYA test? I'm a total newb. Thanks.
