Hey guys, so I've been a long time user of the "cheap chinese LEDs", and I love them, they do a great job. But at my store we've been experimenting with some kessils, and I love what they're doing with the corals. But none of them are on wider tanks, mostly on small cubes. I have a nuvo 16 at home, its 24in long, 12in wide, 12tall. I'm trying to figure out if they will be able to cover that 24in span. I hear from a lot of people that they do good in 24x24 sections. So I want to ask people with experience, before I dish out the money. Also, we don't currently have any of the new controllers, and that brings me to another question. Can the light be left on with more blue than white, and still give the corals the amount of light they need? Or do they have to be on more of a whiter spectrum to supply. I'm just asking because I like a little more blue..but not sure if the corals can survive on it.
