Congrats on the K-2006! Is the pink to clear eaisier for you? It is for me! When doing the chlorine tests, you'll save reagent if you test a 10ml sample instead of the 25ml - you just multiply each drop by 0.5ppm instead of 0.2ppm. You can also usually use just one scoop of DPD powder - if the sample turns pink, you have enough.

Please don't use the Taylor book for anything besides instructions for performing the tests. The book's dosage recommendations ignore many factors that we'll help you with here.

CH of 80-100 is fine for your pool.
You do need more CYA.
Your FC would be good except for your CC reading and the fact that you've probably had some time with no FC recently.
Your FC of 0.6ppm using the 25ml sample shows us that the chlorine in your pool is actively enagaged in oxidising something. You can watch it for a couple days to see if it goes away (or gets worse) or you can shock your pool. I think you should shock your pool.

The shock level for your pool according to Ben's Best Guess Chart is 10ppm FC. You can get up to shock level by adding 2-1/2 to 3 quarts regular 6% household bleach. Test chlorine and add bleach as often as possible to maintain the shock level of 10ppm FC. When you lose less than 1ppm FC between sundown and sunup and your CC is les than 0.5ppm (10ml sample - 0.2ppm FC for 25 ml sample), keep the FC at 10ppm for one more day then let it drift back to normal according to Ben's Best Guess Chart.
