First of all, use the 10mL sample instead of the 25ml so your reagents will last longer.
I don't think you are too messed up at all. If you did the tests correctly, then your numbers are easily tweaked.
Just to verify, when you put the scoop of DPD powder in and the water turned pink, you then add drops of the R-0871 and multiplied number of drops X 0.2. Correct? And, you then added 5 drops of R-0003 and the sample turned slightly pink? Then, added drops of R-0871 until it turned clear and multiplied number of drops x 0.2. That shows your CC level. A CC reading less than 0.5 is not a big deal.
On the CYA test, if the black dot never disappeared, then it means that your CYA is less than 30 since that is the lowest level that can be distinguished. You need around 40-50ppm of CYA. You have a few choices for adding it.
1. Use some trichlor pucks for awhile which will add chlorine and CYA. They are acidic and will push your pH down so you'll have to monitor pH closely and add Borax if it gets too low.
2. Use dichlor powder for awhile. It also adds CYA and chlorine and will build up your CYA level faster. If you decide to do this, buy it at Sam's only. Other places are selling blended dichlor with unwanted stuff in them. Again, will need to monitor pH with use of dichlor.
3. Add some CYA separately and use bleach as your chlorine source.
Let us know how you want to proceed. But, for today, you need to get some chlorine in that pool ASAP before it turns green! Get some bleach in there. Each quart of 8.25% bleach will add about 3.5ppm of chlorine. Since your CYA is so low, you are going to have a hard time getting chlorine to last. I'd go ahead and add 2 quarts now. Then, this evening, test again and add however much you need to get back up to around 6 or so. Until you do get some CYA built up, you are most likely going to have to add chlorine morning and evening so it won't drop too low.
By the way, I think I asked you on your other thread, but can't remember. Those pucks you used didn't have copper in them did they? And, tell me again what the ingredients of the super shock and swim were.
