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.
