When I add the 5 drops of the R003, the solution turns a pinkish color, not a solid pink. When I add one drop of the R0871, it goes clear again. So, I'm thinking I have .5 cc.

Is that right? How pink does it get if you have CC? It's not solid pink like it is after adding the powder, and it's not clear. I'd say it's pinkish.

So if I do have .5 cc, I should be shocking, right? I'm at 40-50 CYA, and went up to 15 TC last night, it's down to 10 TC tonite and I still have .5 CC. Do I have to shock and hold to get the CC down? How long might I expect it to take?

Thanks, happy swimming....
