how much kelvin light does a reef tank need?

is it possible to keep coral alive with almost no kelvin light. just really strong metal halides? would like to know for corals and anemones, thanks.

i set up a 30gal to try it for my self but I would like to know if anyone has any previous experience on what I am about to do. my main fear is the algae growth.
list of what I have as far as lights-
- two 150watt metal halide lights, they give a yellow look (no kelvin light)
- one 20watt true blue light

Halide Lights are the best to use for a reef tank, they usually from 175 watts to 1000 watts with K rating between 5,000 to 20,000. Also they produce alot of heat and require fan cooling. But they are required for Anemons and Corals because they require higher intensity lighting. I would get a stronger bulb but you should get something that ranges close to 9000 K good medium point. Make sure that you pick up a light meter also....

There is a new growing popularity in the reef keeping hobby called Nano Reefs. As the name implies, a nano reef is a reef aquarium on a small scale; 2.5 to 29 gallons. The price of a nano reef is also on a small scale, from the tank itself, the lighting, and it takes less live rock and corals to make a very dramatic reef display.

It was often thought that the bigger the aquarium the easier it would be to keep the water parameters stable. You could not keep corals alive without a massive trickle filter, large efficient protein skimmer, and powerful metal halide lighting lights. The bigger the aquarium the more gadgets you could add to make the water quality pristine, from ozone generators, redox meters, ph controllers, and calcium reactors. You had to be a marine biologist and a chemist to maintain a coral reef aquarium. The nano reef aquarium would seem to go against all these principles. Can we really keep corals alive in a 10 gallon aquarium with no sump filter or a protein skimmer?

What has been learned through the years more than anything is, most of the biological filtration occurs in the live rock and live sand. Lighting has also played a role in enabling the reef aquarium to become smaller with the advent of power compact fluorescent and the smaller HQI metal halide lamps. Having invertebrates that sift through and clean the live sand and live rocks ads to the ecological balance of the tank. Most of the trace elements are replaced through a strict regiments of 5% weekly water changes. There is yet to be a salt water mix that has adequate calcium and strontium levels for good coral growth and these elements should be maintained separately.

The best products to maintain calcium, strontium and other trace elements are made from aragonite, such as AragaMilk from CaribSea. So what is aragonite? Aragonite is fossilized coralline algae that has extracted minerals from the ocean to grow. Grinding aragonite into a fine powder and adding water creates a milky substance that precipitates quickly adding these minerals to the water naturally. Add a few drops to top off water to maintain calcium levels at 450 ppm. You will be amazed at the growth rate of SPS corals. Yes I did say SPS corals that can be easily maintained in a nano reef aquarium.

Fish For The Nano Reef Aquarium

Fish are a great addition to a nano reef, but you must take extra care of you nano. You will have to be sure to keep up with your water changes, because a small body of water can collect nitrates quickly. The following fish are nano reef safe: anthius, true and false percula, banggai cardinals, pajama cardinals, royal grammas, fire fish, clown gobies, pseudochromis, basslets, and most damsels. While you are not limited to just those fish, these are hardy and good for beginners. Keep the number small from 1 to 5 fish depending on the nano aquarium size.

Cleanup Crews For The Nano

A good cleanup crew will keep your nano reef running smooth, and free from algae, detritus, and other unwanted wastes. Commonly kept cleanup crew critters are red leg hermits, red tip hermits, sand sifter starfish, sand sifter gobies, turbo snails, and astrea snails.

Corals For the Nano Reef

There are may corals that are compatible with the nano tank. Soft corals would include zooanthids, zenias, star polops, and mushroom anemonies. Lps corals would include Fox Coral and Blastomusa. SPS corals do well with metal halide lighting. Acroporas and montiporas are the easiest to grow in a 24-29 gallon nano aquarium. SPS coral frags are the way to go in a nano reef. They are much cheaper and easier to ship. The benefits of buying corals online is the greater variety that cannot be found at your local pet store. Buying several items from the same seller can reduce shipping costs. Simply use some Marineland's Hold Fast, which is a two part epoxy similar to plumbers epoxy, to glue the coral frag to a live rock. Be sure to give them plenty of space for growth.
