Hello Hi, I am new to this site, and the hobby ;D. The site is awesome, and I love this thread. I have read the whole thing and is been very informative, but I would like to know a few things because I am very interested in these fixtures. I was looking to get 120 led's with 3 of the big heat sinks, and 30 lights on each heat sink to put over my 90 gallon to have a good amount of light, and no dark areas do you think this is a good idea? Another thing is that I have read that the drivers are cheap on these, but to be honest I don't even know what drivers do :-[ .. So I would like to see if someone can enlighten me on the topic. Another thing is if is true that they are no good which drivers do you recommend? Also which led light combination will be best for optimum coral growth? I want to build a multiple reef with some SPS mostly Lps and softys and polyps but I would like to have the option to be able to put a few Sps. I would also like to have a clam some where down the line .
