Recalibrate Salinity Probe
 

What is the process to recalibrate the apex salinity probe? Mine has been running for over a year and i think it's off but dont know the process.

Thanks

Get calibration solution and place the packet in the sump water to allow it to come to the same temp as the tank water. Use the display to go into the calibration menu and follow the steps on the display. Let it settle for several minutes during the settling process and twist the probe in the solution to insure there are no air bubbles in the probe tip.
