See I always have the budget baller mentality.. when I can save money doing something right the first time I try to do that. I just don't want you to get that "light's fine" attitude then kill both corals and get bad taste for SW especially reefkeeping. Things go south way quicker in a nano so we gotta look out for our "homeys." hahaha. You may be able to ghetto rig two 20watt 50/50 coralife spiral bulbs in there... that would probably allow you to keep some soft corals (zoas, ricordeas, etc.) and they use a standard incandescent socket.
