(Fritz Geller-Grimm) After five years of decline, Baltimore's National Aquarium saw its first attendance increase since 2006 with 2.4% more people attending the AZA accredited aquarium in 2012. According to the Baltimore Sun, the National Aquarium will shift its focus over the next five years from education and entertainment to environmental advocacy. In more positive aquarium news, the state of Ohio was without a public aquarium for 26 years before the Greater Cleveland Aquarium opened its doors on January 21, 2012. In its first year of operation, the aquarium drew over 400,000 aquatic life lovers, thus becoming a financial success for both the aquarium and the City of Cleveland, which collected over half a million dollars worth of aquarium-related tax revenue. Thanks to its successful inaugural year, the Greater Cleveland Aquarium will roll out a new deep sea exhibit on February 16, 2012 as well as lower admission prices for everyone effective immediately. Advanced Aquarist encourages all our readers to visit public aquariums either in your area or on your next vacation. Your support helps makes their education, research, and conservation efforts possible. View the full article

Personally I did not try this light before but one of the way to check is to see if the coral reaction to the lighting , and if it is opening up fully ?

Working in the Great Barrier Reef and under tightly controlled conditions in the of the University of Southampton, the team of researchers produced experimental evidence that the pink and purple chromoproteins can act as sunscreens for the symbiotic algae by removing parts of the light that might become otherwise harmful. Dr Jörg Wiedenmann, Senior Lecturer of Biological Oceanography and Head of the University’s Coral Reef Laboratory, who led the study says: “The beautiful pink and purple hues that are produced by the coral host are often evoked by chromoproteins; pigments that are biochemically related to the green fluorescent protein (GFP) of the jellyfish Aequorea victoria. In contrast to their green glowing counterpart, the chromoproteins take up substantial amounts of light, but they don’t re-emit light. “GFP-like proteins were suggested to contribute to the protection of corals and their symbionts from excess sunlight. This hypothesis has been controversially discussed as the mechanism as to how these pigments function remained unclear. At least for the chromoproteins we know now that they have indeed the capacity to fulfill this function.” The researchers also proposed an explanation for the mysterious phenomenon that some corals accumulate exceptionally high amounts of chromoproteins in growing areas, such as branch tips or in the region of healing wounds. Dr Wiedenmann, who is based at the National Oceanography Centre, Southampton, explains: “These growing areas contain essentially no symbiotic algae, so much of the light is reflected by the white coral skeleton instead of being used by the algae. The resulting increased light intensities in the new parts of the coral represent a potential danger for the algal cells that need to colonise these areas. Hence, it seems that the corals use a clever trick to help their symbionts. The higher light intensity switches on the genes that are responsible for the production of the sunscreening chromoproteins. “Our results suggest that the screening effect of the chromoproteins could help the algae to enter the new tissue. Once the symbiont population is fully established, the light levels in the tissue decrease as the algae use most of the light for photosynthesis. As a consequence, the genes of the chromoproteins are switched off again which allows the coral to save the energy required for their production.” The research contributes to a better understanding of the coral’s response to environmental stress. Knowledge of the stress resilience of corals is an important requirement to help predictions of the fate of coral reefs that are exposed to climate change and various forms of anthropogenic disturbance.

Click through to see the images. On September 1, 2011, Ecotech Marine introduced the Radion XR30w. The highly anticipated LED light was marketed as a "purpose-built" modular, upgradeable lighting system. Ecotech Marine's President Tim Marks remarked at the time: "Our goal was to deliver a product with the ability to evolve and get better over time, not become obsolete." Flash forward a year: On September 15, 2012, Ecotech Marine made good on the Radion's upgrade potential when they announced the Radion XR30w Pro. The Pro is an evolution of the original XR30w and builds on its strengths with additional features and increased output. As such, my review will focus on the improvements the Pro brings to the table when compared to the original, well-known, and highly-regarded Radion. Specifications Model – Radion XR30w Pro Features: 42 energy-efficient LEDs New water-resistant cooling fan Full spectrum output from ultraviolet (405nm) to hyper-red (660nm) Output optimized for PAR and appearance Create custom light modes or use pre-programmed modes Wide light spread with minimal color banding Six channels of control allow users to adjust each color group individually Fully upgradeable modular LED cluster, lens and driver assemblies Capacitive touch exterior controls Wireless synchronization with EcoTech lights through EcoSmart Live Compatible with EcoTech hanging and rail kits to suspend multiple Radions Compatible with the EcoTech Battery Backup Highly efficient heat sink design LEDs: • White: 8 Cree XT-E Cool White (5w each) • Red: 4 Osram Oslon SSL Hyper Red, 660nm (3w each) • Yellow: 2 Osram Oslon SSL Yellow, 590nm (3w each) • Green: 4 Cree XP-E Green, 520nm (3w each) • Blue: 8 Cree XP-E Blue, 468nm (3w each) • Royal Blue: 8 Cree XT-E Royal Blue, 442nm (5w each) • Indigo: 4 SemiLEDs UV, 415nm (2.5w each) • "Ultraviolet": 4 SemiLEDs UV, 405nm (2.5w each) *All wavelengths are the peak emitted wavelength of the LED. Dimensions: Length: 11.8 inches (30 cm) Width: 7 inches (18 cm) Thickness: 1.5 inches (3.9 cm) Max Wattage of Radion Fixture: 170 Watts Max Wattage of LED Channels: 155 Watts MSRP: $899 USD For more information, visit: www.ecotechmarine.com Design The Radion XR30w Pro is an evolutionary product that shares much of the design and components of the original XR30w but with some key changes to enhance its functionality and performance. A look inside the XR30w Pro. Notice the new black LED circuit boards. The most obvious and significant improvement over the standard XR30w is the new LED array cluster. The Pro features eight more LEDs over the first generation XR30w and ten more LEDs over the second generation "G2" XR30w. (42, 34, and 32 respectively). Like the recently announced XR30w G2, the Pro now uses the new 5W Cree XT-E white and royal blue LEDs. The XT-Es are more efficient than the XP-E and XP-G bulbs they replace (and is consequently why the XR30w G2 requires two less bulbs than the first generation). The additional LEDs are comprised of two 3W Osram Oslon SSL Yellow diodes (590nm), four 2.5W SemiLEDs "Indigo" diodes (415nm), and four 2.5W SemiLEDs "UV" diodes (405nm). The 590nm diode - a spectrum bordering between yellow and orange - is centered on each of the LED cluster arrays and was chosen by the Ecotech design team "to provide a more rounded spectrum" according to Tim Marks. The indigo and "UV" diodes warrant a paragraph of their own because few aquarium LED fixtures include sub-440nm "royal blue" spectra, and those that do often output only token amounts. The Pro, on the other hand, includes a class-leading 20 watts of sub-440nm light. Ecotech Marine recognized that lower wavelength bulbs are less efficient so the Radion would require a substantial number of sub-440nm LEDs to produce meaningful light in this spectral range. Thus, Ecotech Marine engineers added eight 2.5W LEDs to provide the bottom end of the spectrum. The four 415nm "indigo" LEDs are a close approximation to the tried-and-true 420nm actinic fluorescent lights reefkeepers have used for decades. The 405nm LEDs are technically not UV (UV is defined as spectra between 10-400nm) but extremely close. The four 405nm LEDs extend the Pro's combined spectrum to encompass nearly the entire 400-700nm photosynthetically active radiation (PAR) range Below are two photos comparing the first generation XR30w (left; upgraded with the TIR lens) and the new Pro model (right; TIR lens are now standard on all Radion models). (Read our review on the TIR lens) Beyond the new yellow, indigo, and "UV" LEDs, you will also note the new white XT-Es produce a warmer colored white light compared to the previous white XP-Gs. Both LEDs are marketed by Cree as ""cool white," yet they look visibly different. You can also easily spot the design difference between the older royal blue XP-Es and the new XT-Es. The Pro also employs a redesigned "water-resistant" and operates at approximately the same volume. The top acrylic panel (including the touch controls and mounting points) remain exactly the same as the standard XR30w. User Interface I will not review the Pro's user interface simply because it is the same interface as the original Radion. Anyone who has used a Radion will know how to use the Pro, and there is an abundance of reviews/documentation about the Radion user interface posted over the past 15 months. The one notable change to mention is the Pro includes one additional control channel (six channels vs five channels on the standard XR30w G1 and G2) to control the sub-440nm LEDs. At the time of this writing, Ecotech Marine is still beta testing their new EcoSmart Live web-based interface, which will of course be able to control the Radion Pro. Note: The beta platform is now open to the public so all Radion Pro owners can use the beta EcoSmart Live if they so choose to. Light Output Dr. Sanjay Joshi plans to test the Ecotech Marine Radion XR30w Pro for an upcoming Advanced Aquarist magazine article. His tests will provide definitive empirical data on spectrum and light distribution. I will do my best to describe the Pro's light within the scope of this review. So the big question is: Just how much more light do the new LEDs add to the Pro? The answer is: Quite a lot. Using our Apogee Quantum Meter, I measured the the PPFD 36 inches directly under the center (in between the pair of LED clusters) of each Radion fixture. Original Radion with original reflector measured 98 μmol m-2s-1 Original Radion with TIR lens upgrade measured 118 μmol m-2s-1 Radion Pro measured 144 μmol m-2s-1. These results tell us the Pro is significantly brighter than the original Radion (even with the TIR lens upgrade): +46.9% more PPFD vs original Radion with original reflector +22.0% more PPFD vs original Radion with TIR lens upgrade (Note: These measurements are for comparative purposes only) Advanced Aquarist does not currently have access to the Radion XR30w G2. However, turning off the sub-440nm channel on the Pro should accurately replicate the G2. With the "UV" and "indigo" LEDs switched to 0%, the PPFD was reduced to 127 μmol m-2s-1, which means the Pro produces approximately 11% more PAR (requiring 15% more power) versus the G2. Graphs by Ecotech Marine But quantity is only half the story of the Pro. What about its light quality? The Pro produces a richer light than the original XR30w. Ecotech does not assign correlated color temperatures (AKA Kelvin rating) to their LED lights because it's an inexact math at best. To the naked eye, the Pro produces a warmer and more natural color rendition than the first generation Radions. While I would describe the original Radions as a cool blue-grey light at full output, the Pro hedges towards a warmer purple-white. We can safely assume the difference is accounted for by the new yellow and indigo LEDs as well as the warmer XT-E white LEDs. And sure enough, when you dial the "UV" channel to 0%, the Pro produces a more cool, grey tone. The sub-440nm do not contribute much in the way of visible brightness, but they definitely add a richness to the light that is hard to describe. It is also worth noting that certain corals fluorescence more under the Pro than the first generation Radion (or metal halides for that matter). This is one unmistakeable benefit where the 400-440nm spectra LEDs can really enhance the appearance of the livestock. Reefkeepers already know that "true actinic" lighting can bring out biofluorescence that higher spectrum lighting can not, so it's not surprising that the addition of the Indigo and "UV" LEDs help flesh out corals' colors. And the Pro accomplishes this feat without making the entire aquarium look unnaturally monochromatic blue. All in all, the Radion XR30w is a true "full-bodied" high intensity light source for the tropical marine environment. Power Consumption The XR30w Pro consumed 171 watts at full power (virtually spot on to the advertised 170W rating) and 8.9 watts when all the LEDs were manually turned off but with the fan running. When the LED light was disconnected from its power supply, the power supply still drew 5.2 watts. Note: The Pro shares the same power supply model as the original and G2 Radion. Conclusion The Ecotech Marine XR30w Pro does everything I expect of an advanced LED lighting system. It is a highly flexible and controllable lighting fixture which provides ample amounts of PAR with "natural" color rendition. The Pro builds on the strengths of the original Radion; It does not reinvent the wheel but rather improves upon a lighting fixture that has been vetted by thousands of satisfied Radion users. And this "modular evolution" concept is exactly how the Radion platform was conceived. I will conclude my review on a personal note: I found previous LED lights (including the first generation Radions) lacked the power or color rendition to replace my trusty 250W metal halide and lumenarc III reflector system used over my 176 gallon reef. The Ecotech Marine XR30w Pro is the first LED unit to impress me enough with both its light quantity and quality that this reviewer has finally decided to make the switch from MH to LED.

Click through to see the images. Palytoxin can be found in our tanks. Maybe not all of them, maybe not even some of them, but it's out there. I do not mean to sound alarmist. However, I do feel the point needs driven home. The more I read online, the more I am convinced this subject needs exposure to reefkeepers everywhere. The veteran reefkeepers know about it, but many newcomers to the hobby do not, and it is important they know in order to better protect themselves while enjoying our boxes of the reef. I am sharing this post with permission, in its entirety for Mario Tango, who posted about his recent experience with palytoxin poisoning. It is another sobering reminder that the creatures we keep do indeed have defense mechanisms and, if we are not careful, we can fall victim to them. We here at Advanced Aquarist wish Mario and his family a speedy recovery and we thank them for their willingness to share their experiences with us. In Mario's own words: Mario Tango's aquarium. The day of 1/10/13 I purchased a few new corals for my 72-gallon bow reef aquarium. On my way home I mentally played with changing my aquascape a bit to fit my new corals, and open my tank up a bit for better flow. 5:00pm and the new corals are acclimating. Since the corals I purchased were Acans, I needed real estate at the bottom of the tank since I am running MH lighting mixed with130w PC actinics. I decided to start re-aquascaping. 6:30pm and the aquascape is now done and looks great. In that time frame I decided to rid my tank of roughly 15lbs of liverock. I had the extra rock that was moved sitting next to the tank in a pot. I wanted to save this rock for later use, but I have no where to allow it to dry out since we live in an apartment complex so I decided to boil it. Yes, this is where the trouble started. [Note: It is not uncommon in the freshwater hobby to boil rock after using it for an extended period of time.] An example of the polyps that Mario boiled. 7:00pm and the rock is boiling on the stove and I am doing my daily duties around the house before my wife comes home from work. 7:30pm my wife arrives home, and on a whim we decided to go out for dinner. By this time the water in the pot is full boil so I cut the stove off and place the pot on the back burner. 8:00pm we leave for dinner and I notice that my nose is tingling much like having allergies. I suffer from hay fever so I know the signs of my allergies coming on. Once we arrived at the restaurant my nose was pouring like I had a cold and my wife started to complain of a tight chest and a cough. We pushed through it not thinking anything of it. 10:00pm and we arrive home and we are both sick. Thinking that we are both getting the Flu or a nasty cold we bundled up warm to take our dogs out (110lb Lab and 70lb Golden Retriever) to do their nightly duties. I feel short of breath and my wife and I have a nasty headache, even though we are completely bundled up we are freezing cold. After the outing with the dogs we sit down on the couch to relax and watch a bit of TV before we go to bed. Both of us are sick and grumpy. Body aches, headache, sneezing, running nose and labored breathing. We call it a night and go to bed. 1:00am and the our Lab wakes us up to a flurry of vomiting. We clean it up and go back to bed feeling worse than when we went to bed the first time. Now we cannot fall asleep. My wife is moaning and stating that she feels like she has the Flu. I feel the same and know something is going on in the house. I don't want to alarm her so I refrain from teller her how bad I actually feel as well. 1:30am and she is asleep but I am noticing both dogs are breathing very heavy and restless. Our Lab gets up and goes into the kitchen and from a weird smell I realized that he defecated. I wake my wife up and we clean it up. by this time she is moaning and groaning. I take the dog out and he walks maybe 20 feet and lays down. Anyone that has a Lab knows this is not typical behaviour for the breed. I got him up, he urinated and the defecated and laid back down. I was finally able to get him in to find my wife back in bed stating that she may want to go to the ER. She stated she felt like she was dying. I have never heard he whimper and moan like this. I was feeling just as bad but pushing through it but felt horrid and almost morbid. 2:00am and I come up with the idea we have mold issues. We had a flood 2 weeks prior that flooded out my car and made its way into the crawl space below our apartment complex. I search and search for mold but cannot find any. 2:30am and I walk into the kitchen again. In the corner of my eye I see the pot of boiled rocks and the light bulb in my head went off like a Nuclear explosion. I jump on the PC and search for coral poisoning and find that certain types of zooanthids find their way onto liverock. This is evident in my tank as there are ugly zoos on some of my rock. I then find that these types of polyps contain Palytoxin. 2:45am and off to the ER for both of us. Prior to leaving I took to pot of rocks and dumped them onto the lawn outside and rushed out. 3:30am and we are rushed into the ER with difficulty breathing. The Dr. and Practitioner see us both at the same time and listen to my story. I explain how I boiled live rock from my saltwater aquarium and think I poisoned myself and wife as well as dogs by these little polyp things that may have been attached to the rock. I still believe that he thought we were nuts and were looking for pain meds. After running our vitals, he finds me with a fever of 101.5, wife @ 101.3 and both of us had high blood pressure readings. He asks me, "Do you guys want any pain meds?" My answer was to the effect of "Doc, we aren't druggies, we don't need pain meds, we need to know what they hell is going on." I think that squared that thought process away in his mind. 4:30am and he comes back with questions about Palytoxin. Imagine that, the doctor is asking me about a toxic substance in corals. He states he has never come across anything like this before and needs more information. I explain to him to read online as there has been a few documented cases of Palytoxin being ingested causing serious side affects. I also explain I am not a Marine Biologist so I do not have any type of information that would pertain to treating it. He states that he has researched it and found a few documented cases, and also called Poison control. Poison control stated that he could only treat the symptoms if the patient was still "alive" and let it run its course. Prior to all this at around the 3:30 mark I would assume, they started IVs and took blood and urine samples as well as chest xrays. the chest xrays came back with symptoms of Bronchitis. 5:00am. After our conversation about poison control they gave us Steroid breathing treatments to ease our difficulty breathing and Tylenol for our fevers. He placed us on heart and oxygen monitors and said that its just a waiting game and he will monitor us for a while and we should both get some sleep. We left the ER at roughly 9:00am feeling much better but still in a lot of chest pain. Two days later, both of us are still feeling the effects of the toxin. When we take a deep breath our chest hurts like we have been in a pool or water for too long. Growing up on the beach we called it being water logged. Our abdomens hurt horribly from the violent coughing we are experiencing. We are both on Ventolin Inhalers and 800mg of Motrin as well as Z-Pack's for any type of bacteria we inhaled. We were also advised to see a respiratory specialist in the near future. Both dogs are fine now, we opened the windows and allowed any residual toxins to vent out. Going back to the point of boiling, I do not recall if there were any polyps on the rocks. I can tell you I quickly examined them for any life just out of curiosity. I guess I missed something. -- Mario Tango View the full article
