Thanks for the input. Don't worry, I wouldn't put the snakes in until everything is right. I was just confused for some reason as to where to put the probe. I had it all figured out for the tanks, but this is different!
I'm sure your smart enough not to put your animals in while you are adjusting. I just said it to save my butt. I don't anyone accusing me of frying thier snakes. I have a feeling that will like the rack better than a tank. Thay are much more economical! Have fun.
