Good morning.

My wife checked the FC level at 6pm last night and it was 7.8. She said the tested water only turned a very light shade of pink when adding the 5 drops of R-0003. That indicated to her that the CC level was near 0. She added (3) 121 oz jugs of 8.25% bleach. When I got home at 11pm I tested and the FC was 20, and similar to my wifes testing of the CC, the water only turned the absolute slightest shade of pink, so I added 1 drop of the R-0871 and it became colorless. This indicates to me that the CC is near 0. This morning at 7:30 I tested again. The FC was at 18 and the CC was similar to the night before.

So it looks like I lost ~ 2 ppm of FC (assuming a slightly incorrect reading as I tested a couple hours after sunrise).

I did not have a chance to scrub the floor and walls as Watermom suggested and there are small areas of brownish, greenish, yellowish patches sporadically on the pool floor.

What do you guys think?
