Today I noticed the lights on the Intellichlor were out (hopefully just a fuse). It may have not been producing for a few days, so I checked the FC and the reading was orange. Has never been this high. How can I have a FC off the charts with the cell not running? And its been +100F here the last several weeks. I did add CYA last week and the FC was about 5ppm then.
Thanks
