Yesterday FC was 5.5. Removed the tabs from the chlorinator and checked this evening and I was down to 3. Just added 269 oz of bleach to bring it up to 10. I have a high CYA of over 100 so I am maintaining a high FC until I can replace water.
WOW FC Dropped

With CYA over 100, you never want to let FC fall below 10. Letting FC go lower risks algae, and once you get algae it will be exceptionally difficult to get rid of unless your bring CYA down.
Retested and I am at 12 now. Water looks great. Wish there was an easier way to lower CYA cause its almost a sin it to remove this water.
