Hi.
my salinity probe has been working correctly for a year + now. No issues.
I decided to give my sump a thorough cleaning and now the salinity probe doesn’t work anymore. It reads in the 60s.
I tried recalibration, and it didn’t work either. I tried manual calibration too with the probe in my sump and it still doesn’t work. Reads in the 60 range.
I have read the countless threads on how to properly calibrate and micro bubbles, temperature, TC factor, letting it dry for a couple days, etc.
But no matter what I try the apex still reads my salt is in the 60 range. I have a refractometer and also a Hannah salinity tester. I calibrated both of them so I know my tank is at 34.8. Any additional ideas besides micro bubbles and stray voltage? I am pretty sure those are not the issues. Could the probe just be broken now? How to know?
thanks!
