Maybe my apex probe is malfunctioning? I picked up an API test (only PH one test I could find locally in a pinch) and the test came back looking like it was either 7.8 or 8.0 (hard to tell between the 2 colors), however, my apex probe is reading 7.43 AND it was just calibrated again.
could it be possible my probe is getting interfered with by something else causing a reading this low? I’ve heard the salinity probes had issues but I haven’t read any reviews with the PH probe being of concern (this is why I purchased the apexEL.
