Temp controller?

[Drock169]

If I put my heater in the sump, should I also put the temp probe in the sump aswell or leave it in the display tank?

IMO....I would keep it in the display tank. Thats where all your livestock is.

Theres prob not a big difference in the sump tank vs. the display tank. But I would want to keep an eye on the tank where all my livestock is.

I keep mine in the display tank as my temp is about 4 to 5 degress different from the sump to the tank.
