It seems like my FC loss seems high compared to other posts I have read. Here are some of my numbers:
On Sunday night my FC was 11, on Monday night it was 5. I added a gallon of chlorine, got my FC up to 9.5 and on Tuesday night it was 5. I added a gallon to get it up to 10, and on Wednesday night it was 6. It seems like I'm losing about 1 ppm overnight and then usually about 3-4ppm during the day. My pool is clear and CC<.5. Do these numbers seem out of whack? Nobody has been swimming...except for a few turtles.
