The first one jeff63851 pointed out is the one I used as a reference. It really was a PITA to find much other info. I used badmans for info and just "winged it" the rest of the way. I really had fun building mine, and the g/f and I enjoy watching ours. Hopefully if more people "get into" paludariums there can be more references. I know I would have liked to have a 'how to' sticky up here, when I was building mine.
Maybe someone on here who is good at writing articles can make one for here? Not sure if enough people on the forum have setups though.
