Several days now and the water has seemed to straighten itself out. It actually has a hint of bleach smell which is far removed from where it was and the cloudiness has dissipated.

This morning...
FC=7-8ppm on a half/half diluted test. It appears to be dropping, albeit, slowly. Using the instructions (multiply by 2), I think this puts me at about 14-16ppm
CC=7-8ppm (appears non existent)
PH=7.2, 7.3
TA=100
CYA still about 100. I still don't know how it got this high. My readings must have been incorrect at close last year.
Clarity on a 1(bad) - 10(perfect) is about 7-8

Going forward I plan to give more attention to the niche light and those hard to reach areas that have proven to be problematic.

Thank you for everyone who contributed their knowledge and insight to this problem. IMO, this forum is the single best resource out there.
