a reef aquarium, lighting is one of if not the single most
important aspects of a successful setup. Most corals sold
in the aquarium trade have some kind of lighting requirement
due to the fact that the are photosynthetic. Varying from
"low-light" soft corals such as mushrooms and green
star polyps which may only need one or two vho or power compact
lamps to intense light requiring clams and acropora which
need a strong light source such as metal halide.
