I am using a Tropic Aire Humidifier and Air Exchanger

I cover the left and right thirds of the lid with tinfoil, and I can fold the tinfoil back if I need to decrease humidity. I'm new to this product, so I can't speak to its long term effectiveness. Also, it doesn't come with an air pump, so that has to be purchased separately. So far I love it. No more misting. No more wet towels. And increasing humidity is as simple as covering more of the top. Because it is an air exchanger, in theory you shouldn't have to worry about cutting off the tank's ventilation. It doesn't create a fog or mist, but I do worry that it might contribute to mold/substrate issues at some point. Fingers crossed.
P.S. I can't wait until Atticus outgrows his tank so I can get him a PVC enclosure!![]()
