ATI Powermodule 48" 6 bulbs 6x54w T5. Recently serviced so everything works great including fans. Will come with brand new fan adapter. Also come with a variety of ATI bulbs that you can play around with for color combo. Bulbs are old. Will work for soft corals or fish only but will need to be changed for more light demanding corals like SPS. $300. Pick up in Irvine. Please PM me if interested.
