I have an apex controller with pH probe that's about 6 months old. I recently calibrated the probe about a week ago. I noticed today that the readings is jumping up & down (8.10,8.13,8.11).. Etc
I have it in the same chamber with my temp probe, ground probe, and chiller pump. I also noticed if I move it in a diff. Chamber in the sump, I get a very different reading.
