So far so good today, I keep checking on the tank (this really is an addictive pet to own!) and with a damp towel on top it's keeping humidity right around 45% which is a huge improvement from what it was.
Ambient temp for the tank is right around high 78 low 80 depending on if the heat in my house is blowing or not.
But what temp should I let the UTH reach before it shuts off? I have it set to 90 right now and kick on at 87, but that is just off of guessing on my part.
