Apex Temp Probe Issues


Active member
I thought I had this fixed but I guess not. My temp probe is reading 3 to 4 degrees higher than what I have it calibrated too. I have this Probe calibrated right at 78.0 and I am running this off of PM1 module and I change the probe name so it does not interfere with the other Temp probe I have on my other system. Right now I have other probes along with a Mercury Thermometer and a Finnex controlled heater with another digital thermometer all reading around 81 to 82 degrees. My probe is reading 77.5 to 78.1 since I have it set as

turn temp on : 77.5
turn temp off : 78.0

I like running my tanks kind of cool and my corals love it but lately this has been an issue for me with this darn temp probe... Anyway to fix this?

Are you looking for a way to adjust the reading the temp probe is giving to the apex? In Configuration>Probe setup>Temp there is an otion that is Ofset. for every 1 point in there you change it the temp probe changes .1 degree I believe. If that isn't the info you were looking hopefully someone with more knowledge then me (which isn't hard to find at all) will chime in. Good Luck
