I have a 150g 5x2x2 and would like to keep a carpet of mixed zoanthid sprinkled with a few other corals (no sps) like frogspawn, hammer, bubble, candy cane, brain, elegance, and pulsing xenia. Question would 6 x 54w 5ft t5's be enough
You should be fine with that. Just make sure the lps is under the bulbs. Keep in mind that if you are just starting out you may decide later that you want more light intensive corals and will need to work with the lighting you have.
