I've got the same one as well. It can handle pretty much anything you want to put under it (limited only by your water quality & flow). There's a guy on a local forum I'm on who runs his LED
nano as an SPS
exclusive tank, with acro, birdsnest, mille, & monti growing at all
levels (but, he also has a sump system that's bigger than the tank itself)...... the lights can handle it.
Thing you need to be careful with is proper light acclimation.... these LED
's can burn some corals if not introduced properly.
