don't mean to hijack - but I've been having a hell of a time with my LPS with Vertex Illuminas over a 18" deep tank at 52% - overall health is suffering, and considered going back to my T5's with some ATI's. My nano tank on the other hand with a PAR33 bulb is a life saver. Any corals that are diminishing in health I drop in there, and overnight they transform.
