Well, the Aquarite seems to be feeling much better.
When I got home this afternoon, I checked the system and the readout was 2800 ppm, which is close to what I assumed it would be.

The diagnostic button revealed the instant salinity to be 2900, pretty close.

I checked Chlorine levels and I was at about 4 to 5 ppm, so I'm at least generating CL.

I checked CYA and I'm out, so I need to up the CYA, bump up the CL and hopefully I'll be set for the season.

Calling the service co tomorrow and canceling the service call, at least until it fails again.

Thanks for all the help!
