Before investing in a reef aquarium it is important to consider the lighting for the tank, which is probably the most important element besides the water quality. Of course, the lighting of the underwater coral reef won't matter if the water is dim and dirty. The water quality is also important for the life of the reef fish, since they require a certain temperature and PH level to survive, and the water must also move a certain way for them to be able to feed. Once this is taken care of, though, good lighting is the next essential for a beautiful aquarium that everyone will be able to see.
Lighting for a reef aquarium not only makes it possible for people to see the fish and the reef, but is also provides the corals with energy that they use to grow. The underwater coral reef contains millions of symbiotic algae, which get their primary energy from light, and they also actively feed for more energy. The symbiotic algae then pass this energy on to the coral itself, making a perfect match. The reef fish also enjoy having the corals in their tanks, which help to replicate their natural habitat.
There are different lighting requirements for different types of underwater coral reef, so those who are planning to put a reef aquarium in their home should speak with an expert on the issue before they purchase any accessories. Short polyp stony corals, for example, require much more intense lighting than soft corals do. When placing corals and reef fish in an aquarium, always check what their lighting requirements are ahead of time.
