Apex heater thermostat

[renato120]

Hi, where Do You guys leave your Heater thermostat?
I have two. cheap one placed on the back glass of the tank.
The Apex is placed in my sump next to the Heaters.
Temperature in the tank with the cheap digital thermostat is 77.7
Apex in the sump is 78.4
I know its next to the heaters so it will not be the same with the one.
Where do you keep yours?
Should I move the Apex thermostat next to the other one in the DT? Is the correct way in the DT?
Thank you.

You want the Apex thermometer upstream of the heater.

Everywhere in a cycle is upstream... LOL
I like to keep mine close to the water return in the sump, but then I have my heaters in the sump too right after the thermometer. The reasoning for me is that I am interested on the temperature in the display tank and not in the sump. Best is to get a good thermometer and check temperature in the tank and see how it compares with apex (then you can keep the way it is, knowing the difference or calibrate the apex to the tank measurement).

The point is not to have it directly downstream in the current from the heater (assuming they're both in the sump) such that you could be measuring false temp spikes.

I got all my probes right next to my overflow if that helps lol and also a temp in return chamber

I got it, but could not help...

Honestly i always see people with 2 different temps from sump and main tank , also had the same problem , not nocking neptune ,i have 3 units and absolutly love them but only one of my temp probes werent correctly calibrated and had to correct it myself

I agree. I have 3 different systems, soon to be 4. I used a reliable thermometer to calibrate all.

I have two cheap ones that reads the same... I calibrate the apex according to those two. I hope Im Around 78
