As above really, how often do you recommend calibrating the GHL probes?

:thanks:

We recommend every 4-6 weeks. With pH probes in calcium reactors they can often last 6-8wks as the lower pH keeps them stable better.

Obviously if you see erratic or out of range readings then it is time to calibrate. Older probes will need more regular calibration.
