Thank you so much Ricky! I went from two layers of newspaper to just one, and it seems to be more stable! I was worried about his hide, but you're absolutely right, he does move it all over the place. I will figure out how to drop my humidity a little bit too. It's weird because my top tub seems to be the coolest, and my bottom tub gets way hotter than the rest. Maybe it's because I had my rack sitting on my carpet. I purchased a wood slab from Lowe's today and I'm hoping that sitting on that, my rack will even out temperature wise.
