It’s time to recalibrate my pH probe that came with my Neptune Apex. I noticed during calibration that the temperature compensation was unchecked. Should that be checked or unchecked? I tried it both ways and there is a difference in readings. I’m just unsure which one is correct. Any feedback on this?
