Where do you all think is the best placement for a temp probe. I’ve been having my ranco’s probe in my return chamber, but it seems that the return would be the warmest place in the tank(after heaters, big pump, fuge lights). The cord is 6ft so I have a lot of options. What do you all think would be the best place to put the probe to ensure the display temp is the proper temperature. The water feels a little colder than 78 to the touch in the display, is the reason why I have concern.
I have mine in the return area of the sump. I have three auto temp probes that I check periodically and they alway match within half a degree. But the sump getting low and reading wrong throws a whole new fly in the ointment in my head!
