There seem to be alot of people looking to get their feet wet in saltwater. I too have considered a small sw tank. Do any of the local stores have starter packages specifically for SW? It seems most of the setups are geared towards FW setup, or require additional accessories to make them SW efficient. And I mean something besides the nanocubes.
Marinescape has the nano but they also have the lighting for smaller long tanks.
You need the tank, and a light- tank is cheaper at ba's, lighting is questionable.
I may have mine up for sale in the near future.
