I'm running the halides on the main tank, and the LED on the anemone tank. The colors are too far off to mix it in with my halides. I think I may use the LED light for a frag tank light, or a desktop office tank (15G with SPS frags from my main tank). There are so many variables to growing coral. It's easy to blame your lighting, but 9/10 times is your water quality. If you have around 300-500 PAR you should be able to grow just about anything.
