Someone please help me settle this discussion. I've read/heard on too many forums that MH lighitng is strictly a reef aquarium fixture. Correct me if I'm wrong but wouldn't it work just as well for planted aquaria (a la Luis Navarro) in a similar setting. From what I've read MH lighting is analogous to running your planted tank on nitrous. Luis may get away with it because he's a master, but those of us who can't balance our tanks on the razor's edge may regret the investment in a sun-tan bright envrionment. Am I wrong to assume that I should stick with the industry standard CF lighting for my favorite rare cS specimens, or should I consider hiking my photosynthetic bandwidth up to true daylight levels?
