I had the water tested and my CYA was indeed very low. I'm adding some right now. As far as the actual cell itself, I recalibrated it to 4500 ppm salt, which was what the easytouch diagnostic showed. All the lights work and it appears to be functioning correctly. After about 6 hours of operation at 60%, I still have no free chlorine. I imagine the low CYA is to blame. Problems of any sort rarely have a one-solution fix.
