Running the SWG at 80% overnight did its job in getting FC up from 2 to 4 so we're moving in the right direction. I'm going to leave it at 80% since we're targeting FC of 5 and see where we are after a day of the sun shining on the pool. The water certainly has that crystal clear look again this morning. If the FC remains around 4 or 5 at the end of the day, then the question is just where I need to set the SWG to have it maintain at that level.
