    For the past four nights, I've been adding 7.5 Gallons of 6% bleach each evening (or 4 gallons 12.5% liquid chlorine, depending on which I can get my hands on). The filter has been running 24 hours per day (pressure did not rise for days until today it went up 2 psi to 12) and the pool continues to look great. I test 1x or 2x per day with the K-2006 and while FC is hovering around 0.5 to 1.0 ppm, my CC has ranged from 1.0 to 1.8 during this time.

    Will this cycle end? I was planning to increase the dosage slightly tonight (equivalent of 4 gallons/10,000 gallons) but wondered if I should be doing anything else. Also, is it normal for water to run a bit yellowish/greenish after pouring in all that bleach? Within a short time (like an hour), it's always back to blue.

    any feedback appreciated.

    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.

    No, I'm pouring the liquid chlorine all around the pool each night, primarily in front of the return jets then I brush to move the water around. Yes, I can take the Mineral Reservoir out and see if things change but then I'm unable to use my tri-chlor tabs. Is this okay for a few days since in lieu of the tabs, I'd be super-chlorinating each evening? Or, am I asking for trouble that way?
