Why is it a new Apex ph probe has to be in a system for some time, like four weeks, before it will calibrate and give an accurate reading?
Working my 2nd Apex install, and getting the same low ph reading that I did on my first, it only calibrated and read accurate when it was in the system for four weeks.
Feedback and anecdotal confirmation is appreciated.
