The Jalli should be good. I think they make a double unit for larger nano tanks. I would definately try to get something a little bigger than a 1g. I had trouble getting my 6g eclipse "eco-balanced" and finally converted it to freshwater. The 1g will be quite a challenge. You'll need to watch evap with the hot light of course too. Also is the tank acrylic or glass. You ever seen the pic of the melted eclipse? It's not pretty. You'd be suprised how well mushrooms and polyps will do under that lighting (13w).
