1. Yes, the cycle will end, but I don't know when. The only way I know to tell is to do a bucket test, with 20 - 50 ppm FC additions, and testing to see when the CC residuals in the bucket end.

2. Regarding the "yellowish/greenish" water. I don't know what that could be. As noted above, the "mineral pack" contains 99.5% of something "inert" but that doesn't mean it can't react with high chlorine. Can you take it out? It's not impossible that it's the source of your CCs. Are you pouring the chlorine in via the skimmer? If so, change to pouring directly into the pool, preferably in front of a return, so it will mix rapidly.
