Guys, Im thinking of converting my nano, QT into a frag grow out tank. Its 12 gal and has the PC lighting. Would this be enough for some softies and zoes, maybe LPS and SPS? I would definetly add a powerhead. What do you think. I have about 15# live rock and a lawnmower blenny in there now and fromia star. Reason being, the little frags from GWA seem to get lost in the main tank.
