I just added a Salinity Probe to my sump. I've followed the Apex setup step by step.
* I'm starting the calibration with probe completely dry
* I'm using the 53000 solution
* I'm using the Apex temp probe and the solution is the same temp
* the calibration is testing 35.1 in solution
* the probe cable is isolation from any Interference
Problem is it reads 31.5 in my sump water when water is 1.025 after cross checking with calibrated refractometer
I know my skimmer pump leaks a little voltage (how much, idk)
Problem.is this skimmer pump works great and it's $300 to replace. Not doing that over a very small voltage leak.
1) is a little voltage throwing a reading of 31.5 in 1.025 water?
2) any way to mitigate this voltage? I've tried a titanium grounding cable via BRS but doesn't mitigate the voltage
