So I added (2) gallons of 8.25% bleach at 6pm on 6/28 when the FC was at 13.8. I got home at 10pm and the FC was 18. I checked at 6am the next morning and it was at 17. I did not add anything all day yesterday and checked the FC at sundown last night (~ 8:15pm) and the FC was at 12. It lost 5 ppm of FC all day. I checked again this morning at 6am and it was at 10, so it lost 2 ppm overnight. I added (2) gallons this morning hoping to get it up to close to 20 again for the day.

The CC is reading 0, so I am a bit confused as to what I am to do next. The pool is taking at least (1) gallon per day to "maintain" FC level.

Any additional help would be appreciated.
