Thanks, Carl!

The instructions with the kit say to add 2 scoops of the powder. Wish I had known you only need to add enough powder to turn the sample pink/red. That must be why my FC reading was so high (?) so I will re-test this evening for sure.

I ran the CYA test properly with the correct measurements of pool water / reagent. I actually ended up filling my small comparator to the brim and the dot was still quite visible. Since the cylinder's lowest registered reading is 30ppm, I can only assume mine must be close to zero. This is not a surprise as I have known all along that my CYA is/was quite low, and definitely below 30. I didn't add it back to the sample bottle (squeeze bottle) but will keep that in mind for future tests. I know the sample is supposed to be somewhat "cloudy" after adding the reagent. It was quite obvious that my sample was not visibly cloudy.

My pool water is crystal clear now and has been since Friday. I will retest my chlorine this evening and post. Can someone tell me a good FC level at which to start adding Di-Chlor again? I have already re-supplied my floater with Tri-Chlor, which is slow dissolving.
