So, last night I calibrated my Conductivity probe... I followed the directions to the letter. When done, my reading was 34.9! Great... I removed it from the solution and put it into my sump. Away from any interference, No bubbles. It jumped to 54/55... Thought that's weird but maybe I have some stray voltage... so I routed the probe cable 2 feet from any power wire and filled a cup with tank water, separate from the tank (sump) to see if I did have stray voltage in the tank... It still read 55. As the water cooled it dropped to 50. Back in the solution, back to about 35. I do have the temp probe on the PM2 (also calibrated) and offset at 2.2 for salinity calibration ... now what?
