What in theeeee, flexxwatt?

[Kaylaaa]

There can be variation through out the strip.
How long have you had it running?
Where is your probe?
FYI, you don't really get an accurate reading with a temperature gun on a reflective surface.

It's been running since last night, I thought it only took a few hours to regulate.
My probe is taped directly on top of the flexxwatt on my top shelf. It seems the top ones are hotter than the bottom.
And should I pull the tub out and scan the inside of the tub? I've been directly scanning the tape.

Edit: How do you fix it if it varies? I'm not trying to have one shelf 100 and one 88 forever haha
