the more i read about lights the more confused i get...im starting to dabble in some corals im learning as much asi can before i dive into it.and when i do research on certain corals many are stated as low, high or moderate lighting needs.I guess my question is simple, but still a little complex.What would be considerd low-2watts a gallon or less?and what would moderate be? cause that would be a great place to start it seems most of the coralsand beginner corals like the moderate to low lighting needs if anyone could help me with this id apreciate it...thanks
