But it's all a individual preference, after looking at a local reefer's tank with 250w MH retrofit SE XM-20k, that's when I decided to go with it. I LOVE the color it gives out. I run 2-175w SE MH 14k and 2-110w VHO Super Actinics on my existing 55g reef, I don't mind it plus my corals are doing great under it. Some people prefer 10k's because it give better growth of corals. But they also have supplement lighting with Actinics. With 20k's, there's no need for supplement lighting. :happyfish
