Just when I thought I had this nailed...
Free chlorine is rising at ~ .5ppm for the last several days to 11ppm this morning even with a progressive drop of the SWG from 65% -> 55% -> 45% -> 35%. I have now turned it off. This last week has been sunny with very high UV, and pretty typical bather load. I have no clue why the chlorine continues to rise given the drop in chlorine generation. With the SWG at 35% Pool Math estimates 1.6ppm generated at my seasonal runtime of 14 hours. Just doesn’t seem reasonable that I would be using only 1ppm in this weather.
I have been testing daily as I get comfortable with the pool and process. Plaster is new as is my use of TFP methods. In the prior two months I was using ~ 2.4 - 2.8 ppm/day depending on weather and bather load. Last week i added CYA to get to my target of 80 (was running at 60). I was almost imediately rewarded with a drop in chlorine usage and was pretty darn pleased with myself. Then it just kept getting better?!?
I suppose it it not the worst of things, but I am getting a bit obsessive with the learning and understanding. The pool water is crystal clear so I am well rewarded for my effort. BTW, if you would have told me last year that my water could be more clear, sparkle more, and even feel better I would have thought you nuts; but it most definitely does!
Thoughts please.
