My tank is 30x30x24, once I remove my btas, I plan on starting a sps dominant mixed reef. now for the past 5 yrs i have been using leds, i have two 120w 16k maxsoect razors. About 2 wks ago I acquired a 6x39w dimmable ati unit. I am currently running the t5s to give them a test run. I may add atinic and blue led strips in front and back of t5 if I decide to continue with it. Those of you who have been in the sps world for a while, or anyone else with experience on lighting please chime in and help me decide my best route to take.
