So, for now, day to day, my SWG percentage is at 45% w/ a salt level of ~3300 and a pump run time of 6 hours per day for a free chlorine level of ~5 at a CYA of ~70. My question is, do I need to decrease that percentage while heating my pool as my pump will run continuously for ~24 hrs at a time in order to keep the FC level at ~5? I figure a longer run time, a lower percentage for the same FC. I ask because I've been checking and noticed that my FC has dropped to ~2 after 4 of us swam for around 4 hours. Is the drop appropriate for the bather load with a pool temp of 90 or do I need to keep my SWG percentage at 45%? Finally, can I offset the drop in FC after swimming for the day by simply adding bleach and if so, how much? Thanks!
