I shocked my pool a few days ago, and have been watching how much the FC drops during the day. My CCs are pretty much at zero now, so I'd think FC would drop during the day as a result of sun, but not quite as much as I'm seeing.
Over the past few days, FC dropped 24 to 15. Then 15 to about 7ish. This is with a CYA of 50. Hence, that means I'm using a gallon of liquid chlorine per day (or more) for a 29k gallon pool. I found an old thread somewhere is it sounded like others were using FAR less than I am.
My pool is direct sun from about 9-6. So that'll take some FC. But it still seems to drop faster than I would think. (especially with no swimmers)
What else would drop the FC? Could the excessive droppings from the trees be a cause? (I'm out there every hour or so skimming all sorts of "thingies" that are coming off the spring trees.)
