Tested FC at 9:00pm last night, it was 28. Tested FC at 7:00am, it was 27, CC =0. Tested FC at 12:30pm, it was 26, CC=0. Water is still crystal clear and does not smell salty. I will let FC go down and test again tonight after sunset and tomorrow morning. If overnight FC loss is 1 or less, I think I will be done, correct?
