it's FAR from an evaporation 'problem'. I've only had it running for <2 weeks and haven't needed to add water yet. I was just noticing how wet the underside of the lid was this morning after having the waterfall overnight. It's never been wet like that before.

I'll buy one of those pipecleaner brushes one of these days and clean the tubing as needed, or at every water change or whatever it needs. I also have about 7 feet of the original 10' left, so I could rebuild it at least twice more.
