I kept the CL at 20 since yesterday and when I came home from work these are my new readings.

FC 10.5
CC 0
TC "Bright Yellow - Off the chart"
PH 7.5
ALK 180
Temp 81

The Algea was not bad and there is no sigh of it today so I think it may be resolved. I was planning on putting my robotic cleaner in. What's up with the ALK ???
