 Saltwater Aquarium Metal Halide Lighting

At Aquatic Connection Live, we offer some of the best selection & best prices on aquarium Metal Halide Lighting for you marine, reef, and saltwater aquarium. There is no other practical lighting source for the reef aquarium that will provide as much light intensity in a small space as metal halide aquarium lighting. This is why they are the most popular for reef aquarists. The need for light intensity provided by metal halides becomes important as tanks become deeper. Generally, metal halides are practical for lighting reef tanks that are 16 or more inches deep and becomes a necessity for tanks deeper than 18 inches. Even shallow tank with more demanding stony corals, such as most Acropora species require metal halides for success.

Do I need an Aquarium Lighting Fixture or a retrofit light?
If you don't have a canopy, you will probably want a lighting fixture that is complete with a hood that can either sit on top of your tank or is hung over your tank. If you have a canopy over your aquarium then you need what is called a retrofit kit. The lighting system and any optional fans are mounted in the perfect spots of the hood for best illumination.

The Glitter Effect
Many people find metal halide aquarium lighting more attractive than fluorescent lighting types such as VHO or power compacts. Why is metal halide more attractive? In natural reef environments surface waves act as a lens that focuses light and create "glitter lines." These glitter lines, familiar to divers, appear as flashes of light of high intensity and short duration and are very attractive to the eye. In reef aquariums these glitter lines, or flashes, can be created through the use of point source lights, such as metal halide lights, and surface agitation of the water. Fluorescent lighting is more diffuse and does not create these effects. Whether this flashing light is advantageous to the corals is not known.

Light Penetration
The intensity of light decreases by the square of the distance that area is from the lighting source. In other words, if you double the distance between the light and the organism, you will quarter the amount of light reaching the organism.

Metal Halides For Smaller Tanks
Metal halides usually put out more than 150 watts (though we do have a 70W metal halide), so they may be too much for smaller aquariums. However, if you use a Pendant, the fixture can be placed some distance from the water, thus reducing the intensity, and spreading the light out better over the entire aquarium.

Check Your Water Temperature
Whenever installing metal halides, be sure to make frequent water temperature checks. Overheating is a potential threat when metal halides are used. However, with good air circulation provided by fans, ( included with all the metal halide aquarium hoods we sell), and a cool air-conditioned house, significant increases in water temperatures may not occur. Chillers can be used to offset any temperature gains if the problem still exists. If you are purchasing a retrofit metal halide system to install in your canopy, make sure you also purchase canopy fans to install. This is nescessary to get the hot air out of the aquarium hood.
