Ok, it went down to the mid-60's shortly after I made this post. I think I figured it out. It was after I changed the water, and when I added more some must have splooged over next to the acu-rite device. Even with the lid completely off it remained at around 80. I stil added a few more holes, just to keep it between 50 and 60 for humid days. I can always tape them up if it decides to drop below 50. Thanks for the help, even though it was a stupid move on my part.
