Click through to see the images. It is true that bacteria has been identified as the main cause of many coral diseases. Take for example "white pox" (not to be confused with "white plague"), which was devastating Atlantic Elkhorn Acropora. It turned out that bacteria from human sewage was the cause of "white pox." Yikes! But as if bacteria, crabs, flatworms, starfish, nudibranchs, snails, cyanobacteria, algae, and heat weren't enough enemies of corals, researchers are learning that viruses can also kill corals. Viruses associated with coral epidemic of “white plague” CORVALLIS, Ore. – They call it the “white plague,” and like its black counterpart from the Middle Ages, it conjures up visions of catastrophic death, with a cause that was at first uncertain even as it led to widespread destruction – on marine corals in the Caribbean Sea. Now one of the possible causes of this growing disease epidemic has been identified – a group of viruses that are known as small, circular, single-strand DNA (or SCSD) viruses. Researchers in the College of Science at Oregon State University say these SCSD viruses are associated with a dramatic increase in the white plague that has erupted in recent decades. Prior to this, it had been believed that the white plague was caused primarily by bacterial pathogens. Researchers are anxious to learn more about this disease and possible ways to prevent it, because its impact on coral reef health has exploded. “Twenty years ago you had to look pretty hard to find any occurrences of this disease, and now it’s everywhere,” said Nitzan Soffer, a doctoral student in the Department of Microbiology at OSU and lead author on a new study just published in the International Society for Microbial Ecology. “It moves fast and can wipe out a small coral colony in a few days. “In recent years the white plague has killed 70-80 percent of some coral reefs,” Soffer said. “There are 20 or more unknown pathogens that affect corals and in the past we’ve too-often overlooked the role of viruses, which sometimes can spread very fast.” This is one of the first studies to show viral association with a severe disease epidemic, scientists said. It was supported by the National Science Foundation. Marine wildlife diseases are increasing in prevalence, the researchers pointed out. Reports of non-bleaching coral disease have increased more than 50 times since 1965, and are contributing to declines in coral abundance and cover. White plague is one of the worst. It causes rapid tissue loss, affects many species of coral, and can cause partial or total colony mortality. Some, but not all types are associated with bacteria. Now it appears that viruses also play a role. Corals with white plague disease have higher viral diversity than their healthy counterparts, the study concluded. Increasing temperatures that stress corals and make them more vulnerable may be part of the equation, because the disease often appears to be at its worst by the end of summer. Overfishing that allows more algae to grow on corals may help spread pathogens, researchers said, as can pollution caused by sewage outflows in some marine habitats. Viral infection, by itself, does not necessarily cause major problems, the researchers noted. Many healthy corals are infected with herpes-like viruses that are persistent but not fatal, as in many other vertebrate hosts, including humans.

Hilbertz discovered that by passing electrical current through seawater, the water would electrolyze and quickly form aragonite (upwards of 5cm thick per year) on the metal cathode. Using his discovery of "underwater mineral accretion," he developed the process of charging submerged metal structure (often made of rebar, wire mesh, or a combination thereof) with low voltage electricity in order to create an artificial structure with high surface area of stronger-than-concrete calcium carbonate substrate. Instead of moving massive concrete structures to restore reefs, why not let nature (with the help of a little electricity) do its own thing on easier-to-transport metal lattice? Divers then attach corals to the new aragonite-coated frames and thus a new artificial reef is born. The corals have been documented to grow at an accelerated rate of three to five times, so it's not long before the artificial metal frame begins to take the form of a natural coral reef. Corals not only grow faster on these electrified artificial reefs; Scientists have also discovered corals on Biorock also fare better against warm climate events and environmental pollution than their natural counterparts! One look at the success of the Pemuteran Artificial Reef Project is testament enough for the Biorock technology. They shared this beautiful video of some amazing reborn reefs.

While every hobbyist realizes lighting is an important aspect of successful reef-keeping, there is still much debate about intensity, spectral quality, and photoperiod. This article will flesh out some of the information I presented at the 2013 Marine Aquarium Conference of North America (MACNA) held in Fort Lauderdale, Florida (I had 45 minutes to present the information which could have easily been a two-day class). I'll present information about how much light is available to the corals The first part of the project was to look at the light intensity in a shallow tidepool. This tidepool is a little different than most in Hawaii in that its depth is not usually affected by tides. This seems a contradiction, so an explanation is in order. See Figure 1. Figure 1. The tidepool discussed in this article. It remains at a fairly consistent depth. See text for details. As can be seen in Figure 1, the elevation of the tidepool is above high tide level, and water enters through a 'blow hole' (at the left in the photograph). Wave energy is focused by a crevice in the rock and the seawater jets upwards and falls into the pool. The water then flows in a northwest direction where it discharges back into the ocean. The depth in most of the pool is about 2 inches (~1 cm) above the top of the corals. Only in times of extreme surge does the water depth become deeper (and then perhaps 18 inches - ~7cm - deep). Figure 2 shows corals growing at the northwest end (discharge) of the pool. Figure 2. A variety of corals growing in the extremely shallow tidepool. The number of coral taxa living in this pool is remarkable and includes Porites lobata, Porites evermanni/ lutea, Pocillopora meandrina, Pocillopora damicornis, and many others. Two of the corals - Porites lobata and Pocillopora damicornis - are considered 'small-polyp stony' or SPS corals and were of particular interest. The invitation to speak at MACNA came in December 2012, and I had to propose a subject for the presentation and begin formulating a strategy to complete the project by late summer. The proposal was accepted quickly, and the clock began ticking. In a few months, I would question my sanity in choosing such an ambitious set of experiments. All I could do was tackle a portion at a time, so the first project would entail collection of light data during a 'typical' winter day in Hawaii. This may sound like a day at the beach, but many problems had to be overcome. First, my data loggers for PPFD (or PAR) failed to operate. They had served me well for years, so I ordered a newer model and software from Spectrum Technologies (Aurora, Illinois, USA). While waiting for the order to arrive, I began scouting for an appropriate spot to deploy this equipment. It had to meet several criteria. First, the tidepool had to be easily accessible and within a reasonable distance from my laboratory. It had to be in a relatively flat area in order to avoid early morning and late evening shadows. The depth would have to be fairly shallow and relatively free of strong surge (even small waves can toss and overturn a quantum sensor anchored with a five-pound dive weight). The area had to be secure in case I needed to leave the equipment unattended for a few minutes. After evaluating several sites, a small tidepool north of the village of Kailua-Kona (west coast of the Big Island of Hawaii) was chosen. It was now the first week of February, thirty-something days since the invitation was accepted. Less than eight months remained before the conference, and not one bit of data had been collected. In addition to all the conditions listed above, the day would have to be relatively cloud-free in order to get the info needed to start the project. The crystal ball for Hawaii weather is also a bit cloudy (no pun intended). I would have to watch the weather reports on the local news (no Weather Channel available on Big Island cable TV. No need - it is usually 'nice' and 80F - ~27C). The stars and planets would need to align - clear sunny weather all day and the equipment (data logger and computer-driven spectrometer) would need to be in place before sunrise AND function flawlessly all day. As it turned out, the first attempt was not successful. The clock was still ticking and meaningful results remained elusive. My stress level began to climb. Fortunately, the second attempt was successful. The Figure 3 shows the results. The PAR data logger recorded PPFD values at a depth of two inches every minute for the entire photoperiod, for a total of almost 700 measurements. An Ocean Optics USB 2000 spectrometer recorded tens of thousands of spectral data points as well. Light quality will be the subject of a future article. See Figure 3 for PPFD values. Figure 3. Underwater Photosynthetic Photon Flux Density (PPFD) at a depth of two inches. Hobbyists often call these values PAR (for Photosynthetically Active Radiation). As Figure 3 demonstrates, the sun rose at about 7 am and set at about 6:15 pm, for a photoperiod of approximately 11.25 hours. The weather remained clear (with only slight amounts of smoke from the nearby volcanoes present) for most of the day. High clouds were present for only a few minutes in the late afternoon (about 3:45 to 4:30 pm). The PAR sensor takes snapshots of very short duration and the 'glitter lines' generated by waves generated by surge or wind are apparent at 10 am to ~4pm. Figure 4 shows the data with a trend line and allows us to judge smoothed information. Figure 4. The underwater PPFD data with a polynomial trend line. As we can see, the smoothed data shows a peak PPFD at about noon of ~1,000 µmol·m²·sec. The inserted photo shows the WatchDog datalogger and sensors. Finally, I had some usable information and my stress level began to level off. Now the data analyses could begin. Daily Light Integer Instantaneous PPFD values are of great value but tell only part of the story. The best comparison is to compare PPFD to rainfall. An instantaneous PPFD value (the number of photons falling on a given surface area in a given amount of time) is equivalent to the number of raindrops falling on an equal area and time. We would find a weather report presenting rainfall as number of raindrops falling on a square meter per second to be practically useless. We are more interested in the total amount of rainfall reported in inches or centimeters. The same is true for light - we should be interested in the total number of photons in a given photoperiod. This is called the Daily Light Integer, or DLI. The DLI simply sums the total amount of photons falling on one square meter per photoperiod (in hours). It would be a tedious task to add up all 700 instantaneous PPFD measurements. Fortunately the WatchDog software does this with only a couple of key strokes. Figure 5 shows DLI values for above and below the water line. Figure 5. Total amount of light above and 2 inches below the tide pool water line during an 11.25 hour photoperiod. Only 65% of the surface light reaches a depth of two inches. Conclusions and Discussion The west coast of the Big Island of Hawaii has some healthy coral reefs (but the number of coral species is relatively low). Although the latitude there is only ~20 north of the equator, it is still subject seasonal changes in solar radiation (Key West, Florida's latitude is about 25N.) Of course the amount of light and photoperiod is less and shorter, respectively, than in summer, but the information presented here is representative of a typical winter (February) day. As any visitor or resident of the Big Island knows, the island is still an active volcano, with two open vents currently spewing tons of noxious gases into the atmosphere. Undoubtedly, this mixture of volcanic gases and smoke ('vog') from burning forests (caused by lava flows) lessens the amount of visible light falling upon the earth. Vog also absorbs some ultraviolet radiation. However, vog was not present in great quantities on the days the data loggers were deployed. As we have seen, lensing effect of passing waves creates 'glitter lines' and the instantaneous amount of light can be highly variable at a depth of two inches in the tide pool. When a trend line is added to the data, we see the maximum underwater light intensity at noon is about 1,000 µmol·m²·sec. The total number of photons (or DLI, as shown in Figure 5) is also affected by sky clarity but more dramatically by water depth. The depth is quite shallow and we cannot escape the effects of solar elevation and water surface reflection. Since the sun's elevation is lower in winter than summer, the light's angle of incidence is relatively high and some of the light is simply reflected by the water surface. Hence, in this case, approximately 35% of the sunlight is reflected or absorbed by the water (there is also the possibility that light is scattered by particles suspended in the water column, an effect called turbidity). The Daily Light Integer (DLI) gives us a chance to compare natural light dosage to that in an aquarium. Can we possibly match the amount of natural light in an aquarium? We can answer the question with simple math. Example A coral in an aquarium receives 500 µmol·m²·sec and the photoperiod is 12 hours. What is the DLI, and how does it compare to the tide pool? Remember, we want to calculate the total number of photons falling on a surface during the entire photoperiod. This is quite easy in an aquarium, since the lights are either on at full intensity, or off, in many setups. 500 µmol·m²·sec * 60 seconds in a minute * 60 minutes in an hour * 12 hour photoperiod = 21,600,000 µmol photons. This number is unwieldy, so we divide by 1,000,000 to convert µmol to mol photons. Our DLI (in mol photons in a 12 hour photoperiod) equals 21.6. The tide pool DLI is 22.3, so an aquarium coral receiving 500 µmol·m²·sec in a 12 hour photoperiod is receiving just about as much light as a shallow water (2" depth) coral does in Hawaii in February. If we bump the light intensity upwards to 525 µmol·m²·sec and the photoperiod remains at 12 hours, we would exceed the natural winter DLI. Of course, we could lower the light intensity and extend the photoperiod and get the same DLI. The first sets of data were collected. Time course light intensities (above and below water) were recorded. The computer and Ocean Optics spectrometer had done their jobs and spectral data were now available for analyses. As it happened, I would collect a second set of light data. Just to be sure, or more likely, I'm a glutton for punishment. Some pressure was off. The analyzed information showed the amount of light in the tidepool and that it could be matched in an aquarium. Many questions remained. How much light did the tidepool corals actually require? How did they respond to high light intensity - did their zooxanthellae possess unlimited adaptive processes or was this tide pool a hostile environment where corals took a licking but kept on ticking? What is the spectral quality of sunlight at this shallow depth? How does the underwater spectral quality compare to aquarium lights? I realized the amount of work facing me and the stress started to return. The relentless count down to the MACNA conference continued. I would need to generate enough information to make a 45-minute presentation. What I had could be discussed in a few minutes. There was no guarantee any of the future data would be of any use. What had I gotten myself into? Next time, we'll look at the light requirements of these tide pool corals and how they use (or don't use) available solar energy. View the full article

Actually i mean this is not an easy coral to keep, it need good flow and feeding. Try sponge power from Zeovit if you can get some from freshnmarine.

Click through to see the images. Since Vortech's EcoSmart controllers do not have USB ports, there was no other way to program Vortechs except by interacting with the physical controller's mode buttons and control dial. But since EcoSmart controllers have built in RF wireless ability, users will soon be able to control their pumps using Ecotech's newest product, the ReefLink. This means that Vortech owners will be able to program their pumps on the fly from any web-enabled device from anywhere in the world. For more information about the ReefLink, please read our hands-on preview. The ecosmartlive.com's preview of the Vortech schedule screen is a non-interactive screenshot at this time, but it shows that Vortech owners will be able to manage their pumps like never before. Not only is the web-based interface much simpler to use than the button-combination method required for the physical controller, but Vortech users will have a lot more flexibility in programming their pumps for different modes throughout the day. Moving to a web-based control system just makes sense. The interface is much more streamlined. It allows "program-anywhere" controllability. It helps integrate products across Ecotech's lighting and pump platforms. Who knows? Perhaps one day you'll be able to set a complete simulation of a natural coral reef for your reef aquarium with a few clicks of your mouse (or finger touches on your tablet/smart phone).
