Yes stabilizer is the same as CYA, but the problem is that the pool store doesn't take it into account as affecting the level the FC should be. They recommend that the FC level be 1 to 3 ppm no matter how high the CYA is.
I suggest you test in the evening before adding bleach. You need to make sure you are not dropping below the min FC (for your CYA level) and you will have your test #'s needed to calculate the evening dose.JeepGirl said:Ok, I received my TF 100 test kit today. I put in 96 oz of bleach again tonight after the daughter and her friend got out of the pool. It was dark, and was very sunny today, so figured I would just do as I have been doing since Sunday per advice from Dave earlier.
When is the best time to test? First thing in the morning, or in the evening as the sun is going down when we add the bleach??
