Hmm, I feel like we have been here before...Anyone else getting a sense of de ja vu!

UTH setup: UTH, UTH probe, enclosure, (in that order) thermometer probe inside enclosure on hot side...If you want one on the cold side also, feel free. Buy another thermometer and throw it on in there!

CERAMIC (any rhp): Heat is above, my thermostat probe is inside the tank on top of the substrate (this is a viv set up the probe is secure, my others are tubs) I also have thermometer probes etc. I throw them on in there too! This is how vivarium set ups are done here by the rep shops, I took their word that this was correct

This is how I do it. I'm not saying I'm right!
