Just for air circulation. The air comes out of the central stump into the vivarium. They do a good job of keeping the glass clear and drying out the plants after the mister goes off.
Here's another couple of pics:
This one is before painting. It shows the paludarium while it was still a 'fish' tank. At this point I'd moved all the inhabitants to different aquariums. I had been more interested in the emergent and above-water plants for a couple years.
So the first step to making this work was to put a pretty thick bead of silicone on the bottom of the tank. This serves the dual purpose of adhering the structure to the tank and sealing it so the water can only go through the poret foam mattenfilter for filtration.
