I recently posted that after a week of shock, I was still not passing the overnight drop test. (I found out I wasn't dilligent enough about keeping it at the target level and brushing. So I raised the shock level from 16 to 18 to give me a little buffer.)
After really getting after it, here are my numbers. I know I probably kept it at shock longer than required, but after a coyuple of weeks of battling algae, I wanted to make sure.
Am I correct that I am ready to go back to Target FC?

Water is crystal clear, brown and white particles collect at vinyl seams on floor during the day.
