I THINK my UTH is Zoo Med but I can't remember exactly. I'll have to take a look.If it is I might just take it off and start taping it back on as that'll be much easier cleaning-wise.
As for the humidity thing, I have been covering most of the lid of his tank with a damp towel this past week when I saw he was going into shed and it helped perfectly.
I'll have to look into getting him into a tub, it'll be much easier!
