I wouldn't suggest repti-carpet. Bacteria will have a field day in his tank. I would give paper towels a try - you might like them. And they really don't look all that bad in a glass enclosure.
OK temp gun is a good thing. I must have missed that. Sorry. Regardless the sticky gauges are still inaccurate.
I don't see any harm in the waterfall. Most BP's (as far as I know) aren't soakers unless they have mites
Also to keep humidity in a glass enclosure you could do something like this...
I went to walmart and got some thick(ish) vinyl from the sewing dept and cut it to fit over the screened portion of the enclosure and cut out holes for the light/air circulation. I rarely use the red heat lights....mostly cold winter nights![]()
