I am thinking about changing my lighting on my 40 gallon. I currently run 2 150 watt de halides. I was thinking about changing to a single 250 watt se retor from hellolights. I may also get some t5s for supplement lighting, not sure yet. Would a single 250 watt be better than the 2 150 watts? I keep mostly sps and clams as my main focus in my reef. Please share your knowledge with me on this.
