One area of fish keeping often neglected is aquarium lighting. Effective lighting not only enables you to view the contents, but it also enhances the colour of fish, plants and invertebrates. Inappropriate aquarium lighting may not only have a direct effect on the welfare of plants and corals, but may also impact the health of fish.

The health of many species is directly related to the quality and quantity of light they receive. They use the energy from lighting as a means of powering photosynthesis on which their health depends. Those that  concern us most are the microscopic symbiotic algae, or zooxanthellae, which inhabit the tissues of many marine corals, and the tropical aquatic plants that we grow in our freshwater aquariums.

	Reflector Lights Reflector lights is an ideal means of adding a primary light to almost every  aquarium, and is also an effective means of supplementing an established lighting system. The lights can be installed within a hood or added to an existing aquarium or top aquarium. The standard tube fittings ensure that one can install almost any form of T8 fluorescent bulb to suit the requirements of most species, while the polished aluminium reflector ensures that maximum light is directed into the aquarium.
	Metal Halides Metal halide lamps may be regarded as the only form of lighting that is capable of providing the intense lighting required by many corals and plants. The 'rippling' light effect associated with metal halides provides an attractive feature, mimicking the wave-induced flashes of intense light that enhances the growth of many corals. However, many corals and plants also require a combination of fluorescent lights to provide them with a specific spectrum or colour of light. By combining a high light intensity metal halide bulb with a range of colour spectrum that is associated with fluorescent bulbs, the Aqua One combination system will meet the needs of the most demanding coral or plant.
