my humidity levels have been fine for months, but my fogger broke and after we took apart the tank to replace it, i cant get the humidity back up to the 70's, ive tried blocking the screen at the top of the exoterra tank, i've tried misting but the humidity levels just keep falling. but the thing is due to the amount of fog and condensation and the natural humidity levels were i live there is no whay the humidity should be that low. ambiant here is 50 sometimes 60 and it's fallen below 50. the frogs seem fine though it makes no sense. nothing changed besides the fact that we took out the waterfall because it kept clogging, but the water-fixture (a 2 gallon pond) is still their and so is the small fountain, it's just not dribbling down from the top ot the cage any more. any suggestions?
