My P.O.P. is gone. need help again

A dog is equivalent to many bathers and if the kids urinate in the pool then that can also create a large demand, but it sounds like this happens every day for you, not just for such one-time incidents. Are you saying that if kids and dog do not get into the pool and there is just sunlight that the FC doesn't drop or are you saying that it does? I'm trying to understand if it's specifically the introduction of the kids and dog that are causing the drop.

Theres been very few days that no one has been in the pool. Its been 2-3 months since I have covered it. The other day was the first time covered. It wasnt a very sunny day and no one had been in it. I think it dropped 1 or 2ppm in 11 hours. If I remember correctly it has dropped uncovered full sun with no one in it. Its yo yoing too much based on replies. Just last night it was 9ppm covered and this mourning 8. No one in it yesterday except 2 frogs. the kids get out to go pee and so does the dog. It does drop sharply when we are all swimming. I would have to put bleach in it all day to maintain 10ppm
