I was recently given a 210gal tank by a friend and I'm in the process of planning what to do with it. My biggest question obviously, is lighting. Now, I wont be to a point where I need to commit to a certain lighting scheme for a while so I figure that this is the perfect time to talk about it. The obvious first choice is a MH/actinic combination, but I'm really interested in the progress the new LED lights have made. The tank is 84x24x24 so theres not a light bar made that long that I can find, and I'd like to mount a system inside a hood. I know that with MH I can use a 72" bar and it will reflect to the edges, but I'm not sure if the LED bar can do the same. On the other hand, the MH will require a chiller and more energy consumption than the LED will. Initial cost is not a major problem because I'll simply save longer to get the more expensive fixture before I start if thats what I need to do. I've read anything I could find on the Solaris lights from the manufacturer and advanced aquarist, and I've tried to stomach my way through the threads at reefcentral about this topic, but I can't get past the backbighting and petty arguments they have on the thread. What I'd like is an intelligent discussion about the merits/problems of each system so I can make an informed decision. I don't know if anyone but Tangster has had any experience with the LED system, but if any of you guys have one, or know someone who does, How does it work, look, etc. Were there any technical problems initially? Does it spread enough to cover an additional 6" on either end of the tank etc. etc. etc. Thanks in advance for any advice you guys have on the topic.
