If a mats heat reaches 85-90 y would I need a thermastat ???
The top one on the heat matt in the middle is 75-80
The bottom one is 79 so I don't need a stat????
Not sure what those mats are up to then. 75-80 is OK for the cool side, but needs to be warmer for the warm side. I'm confused to be honest. A mat without a stat can (and probably should, according to its design) run well over 110 degrees. It's unlikely that both mats are on the blink.
I suspect the light's stat is switching it off because the temp has hit whatever you have the stat set to and then the mats are maintaining it so the light doesn't switch back on.
Are the stat probes actually on the floor of the tank, on top of the mat surface, and is that where you're measuring the temp?
I'm really scratching my head as to what's going on. The basics are:
- Floor at the warm end needs to be in the mid-high 80s
- Belly heat is better than overhead heat
- A heat mat needs regulating to keep it in the 80s (or at least, it should!)
- Light isn't necessary for the snake
Quite how you'd go about getting that temp at the warm end given the odd way your setup is behaving, is beyond me at the moment I'm afraid.
