Lighting. So I found Radion xr30w Pros. I assume this is what was mentioned? Is the 30w the highest output? I found them in one store for $899. I assume that I could find them for perhaps a little cheaper if I did some digging. They don't appear to be very wide though. I haven't found a dimension for the entire hood, but it looks like they're about 16" wide and 12" deep. If so, 3 may not cover the tank well. I may need 4-5. I don't mind if the ends of the tank are a little dim--I can put low-light corals there. I just don't want the tank to be light-deficient or look weird because of too little light. How far above the tank can you mount these? I don't want bubble popping and covering the lenses with salt all of the time. I also don't want concentrated beams of light--or a "spotlight effect" from each bulb. Do they blend well? And as for the controller comment, I assume that you mean a light/powerhead combo controller? If so, I agree, but don't know anything about them. I assumed that the lights would come with one.
