We chose Okinawan stony coral for a variety reasons (which are actually "mined" from the Rukuyuku Islands of Okinawa - where the fossilized stony coral sits in the same pure, pollution-free state in which remained for thousands of years).
Coral calcium is a valuable, holistic, mineral, dietary supplement which poses many important issues, ranging from discussion about our current mineral-depleted Western diet to concerns about the ecology and future of coral reefs....
One of the common health claims concerning coral calcium is that it bestows longevity -- wherein the longer lifespans of Okinawans as compared to their mainland Japanese cousins (as well as Chinese or Koreans) is the result of coral consumption.

 What are Coral Reefs?   (Site not responding. Last check: 2007-10-29)
Stony corals (scleractinians) make up the largest order of anthozoans, and are the group primarily responsible for laying the foundations of, and building up, reef structures.
While the growth patterns of stony coral colonies are primarily species-specific, a colony’s geographic location, environmental factors (e.g., wave action, temperature, light exposure), and the density of surrounding corals may affect and/or alter the shape of the colony as it grows (Barnes, R.D. Barnes, R.S.K. and Hughes 1999, Lalli and Parsons, 1995).
Although living corals may be scarce except near the seaward section of this zone, its many microhabitats support the greatest number of species in the reef ecosystem, with mollusks, worms and decapod crustaceans often dominating the visible macrofauna (Barnes, R.D., 1987; Lalli and Parsons, 1995; Sumich, 1996).

Coral pigments cannot directly transfer collected light energy to the corals symbiotic algae, but in some deep water corals their pigments appear to be modifying the existing light field by fluorescing one color or wavelength of light into another color or wavelength.
Corals in shallow water can theoretically use this pigment to shield themselves from the harmful affects of UV light, while corals in deepwater can modify the UV-A light into light that is more photosynthetically useable.
If you plan on releasing your stony corals into the natural environment (captive farming to replace natural populations) it would probably be a good idea to have them acclimated to strong UV exposures.

The stony coral calcium powder is harvested from land areas where the coral calcium powder is mined, much like table salt is mined.
Coral calcium powder is a masterpiece of nature in that coral calcium powder becomes ionic immediately in water for absorption and use by the body.
Coral calcium powder then greatly increases the oxygen level in the body, allowing the body to rid itself of toxic wastes that are constantly accumulating.

Coral reefs are the least abundant of the benthic habitat types, estimated to comprise approximately one percent of the sea floor within the Florida Keys National Marine Sanctuary (FKNMS).
The relative loss for stony coral cover was 50 percent or greater for both shallow and deep reef stations.
As the coral reef monitoring is integrated with the seagrass and water quality programs, the results can be used to focus research on determining causality and can be used to fine tune and evaluate management decisions.

 Coral Reef Biology   (Site not responding. Last check: 2007-10-29)
As a result, the distribution and growth of corals is strongly light-dependent, as is the overall growth of the reef (Levinton, 1995).
Corals that must obtain nourishment from outside sources (heterotrophic) typically are spheroidal and have a single-layered skeletal structure (Barnes, 1987).
Soft corals can be overtopped by stony corals, but their rapid growth and distastefulness to many predators allow them to rapidly colonize any newly-opened space (Barnes and Hughes, 1999).

Coral Calcium or fossilized stony coral minerals are a holistic mixture of minerals in variable amounts.
In general, the main elements found in fossilized coral or “coral calcium” are calcium and magnesium.
The term “marine coral minerals” refers to the fact that both ocean and land based coral material are examples of fossils which are derived originally from a marine environment.

Pair wise tests were run for total stony coral and individual species with adequate data., to determine whether there was significant change in number of of stations with presence of a certain disease/condition from 1996 to 2000.

 Wildlife of Sydney - Fact File - Stony Coral
Few stony corals grow around Sydney but of these, Plesiastrea versipora is most often noticed by divers.

 Past Stony Coral Growth (Extension) Rates on Reefs of Broward County, Florida: Possible Relationships with Everglades ...
The skeletal growth of hermatypic (reef-building) corals is a sensitive indicator of environmental conditions and perturbations.
Normalized annual growth (linear extension) rates of corals from Broward County, Florida were studied for a 26 year period from 1985-1960, with a common record for all corals of 16 years from 1985-1970.
Therefore, it is unlikely that the strongly significant correlation of coral extension with sea water density is attributable to temperature effects on salinity as this should also have been evident in the temperature-extension correlation.

The right half of this window is dominated by a group of larger polyp stony corals, including Plerogyra (the bubble corals), Lobophyllia and Symphyllia (often called “open brain corals” and Cynarina.  These are lagoon corals, often inhabiting murky inshore waters, and are thus among the easier stony corals to grow in captivity.
These corals all have fleshy bodies extended out of their calcium carbonate skeletons, giving them the appearance of being soft-bodied animals like anemones.
In the upper shallow area of this window, there is a group of colonies of Montipora verrucosa, a small polyp, reef-building stony coral originally from Hawaii.  All of these colonies are genetically identical, being produced through fragmentation of an original specimen that we received from Marine World in Vallejo.

The fossilized stony coral calcium Dr. Bruce Halstead produces is best called 'marine coral minerals' or 'stony coral minerals', and the primary nutritional elements found in this coral calcium supplement are calcium and magnesium.
While it is true that the above sea level coral calcium contains lower levels of magnesium than below sea level coral calcium, Dr. Halstead believes high levels of magnesium are not required in coral calcium.
Mining coral calcium from above sea level also avoids the potential of heavy metal contamination that is associated with any product that comes from the ocean and sea bed.
