In manual, Ph 7 and 9 is for aquarium while 4,7 is for fresh water. Yet, my ph probe mainly measures between ph 6 to ph 7.8(or elese but not higher than ph8).
Thus, can I calibrate the probe with Ph 4 and 7 for my aquarium?

Calibrate with the 7 and 9 fluids because your average pH levels are closer to this range.
