I have a tank setup with a small water bowl and foil covering most of the screen top. The humidity has been pretty high lately, running 80 to 85, primarily because of the climate here.

Is it bad for the humidity to be that high for days on end? Should I remove the foil at the top to try to drop the humidity when she is not in shed? I don't want her to get a RI or something. There is no mold or moisture building up that I can see, her tank is clean, it is just humid here in the summer.
