I have a 10 gallon tank with 20 lbs live rock, 2 PHs and a nano-skimmer, right now I just have a 15 watt 10000K bulb on it so it's FOWLR at the moment. Was contemplating upgrading the lights; for a 20" tank I think there are 36 watt PC bulbs that would fit. Not sure what the rules of thumb for watts per gallon are for the various corals; (I'm a FW plant person mostly!)....if I got this lighting what kinds of corals could I grow? I'd be looking for less demanding corals. The other inhabitants of the tank are 2 feather dusters, some Astraea snails and a 6 line wrasse.
