The abstract for the paper summarizes: Our results, in combination with recent findings suggesting range expansions of tropical coral‐reef associated organisms, strongly suggest that rapid, fundamental modifications of temperate coastal ecosystems could be in progress. Formely temperate waters will increasingly serve as refugia for tropical corals and organisms. The study also concludes that "in regions with poleward current flows (east coast of the United States [Precht and Aronson, 2004], east coast of South America, east coast of Africa and east coast of Australia [Figueira and Booth, 2010]) the speed would be much greater."

A newly constructed, 2,000-year history of sea level elevations will help scientists refine the models used to predict climate-change-induced sea level rise, according to an international team of climate researchers. The record also shows that the past century had the fastest recorded rate of sea level rise. View the full article

As reported earlier on Advanced Aquarist, the California Academy of Sciences' Steinhart Aquarium has a pair of Ornate Ghost Pipefish (Solenostomus paradoxus) on display which have released larvae in captivity. Since our last update we've been able to observe mating several times, and Academy biologist Rich Ross has captured it on video. Check out the video below to see the entire process of ghost pipefish reproduction--from mating, to a close up look inside the female's pelvic fins where she holds the developing eggs, to larval release. So far we have seen the female release between 20-50 larvae every morning for the last 8 days, followed by mating with the male as soon as we place them back together. Is this typical behavior for the species, or an artifact of captivity? Does she hold eggs and larvae of different age in her pelvic fins at the same time in the wild? Before you go rushing out to obtain a ghost pipefish or two, you should be aware that the vast majority of these amazing animals collected for the aquarium trade die before ever reaching their intended destination. Those that do make it are often extremely weak from the journey. The individuals described here were carefully collected and shipped by Steinhart Aquarium staff from a shallow seagrass bed in a small Philippine bay to a display tank in San Francisco within less than 36 hours. Along the journey, they received several water changes and were always held in enormous containers. It is our firm belief that this extraordinary level of care during shipping is necessary for these fishes to arrive alive and in good health. http://vimeo.com/25210712 View the full article

Wow i forget about this new products. Do share with us if it work well

Wow.. that would be the best combination i feel . I always wanted to supplement my tank with two single tube T5 HO on both side of my LED, but the cost of customizing it is not economically at all .

If you did a search on the forum here there has been a discussion on this before. It work on the same principle as Bio pallets by providing a carbon source for the bacteria, but it has to be used with caution especially those keeping a SPS tank .

Can consider the new multiple test kit from DD or ELOS.

Chances are, you've never heard of seneye ... but soon, they will likely become a household name amongst aquarists. seneye is a new company founded by a small group of dedicated fish keepers who saw a need for a product that can constantly monitor and relay critical aquarium parameters in a simple, effective, and affordable manner. So they set out building this product without any investment from big businesses or venture capitalists. And this is the fruits of their ambition and labor: seneye will be introducing three versions of their new advanced monitoring sensor: the seneye Home, seneye Pond and seneye Reef. A small, rectangular, all-in-one sensor is mounted underwater (via a suction cup) to provide constant monitoring. Of particular interest to Advanced Aquarist is the seneye Reef. The seneye Reef includes a PAR, LUX and Kelvin meter along with free ammonia monitoring, pH monitoring, water level monitoring, general light monitoring, and temperature monitoring. phew! The seneye Reef features: Automatically monitors multiple key parameters Constantly watching your aquarium with 5600 readings per month Grow healthier coral with the assistance of the integrated LUX, Kelvin and PAR light meter. Early warning, intelligent software predicts future water conditions Convenient alerts sent to e-mail and mobile phone Access results worldwide. Your data is stored online Track your results with automatic graphing Connect to a PC or optional USB power adapter In total, the seneye Reef monitors: free ammonia (NH3)* pH* light monitoring temperature water level LUX (lx) photosynthetic active radiation (PAR) kelvin (K) * requires consumable slide which lasts for 1 month and makes nearly 3000 readings each month. Connect your seneye Reef to an internet enabled PC and receive feedback about your aquarium. Your seneye monitoring data is recorded online on seneye's server, accessible anywhere in the world at any time. Access to their server is free of charge. In fact, seneye plans on allowing non-seneye aquarists access to their server where they can manually log data. A seneye mobile app integrates with seneye's server and offers a clear overview of your aquarium's status. A 'green' dot identifies safe parameters, while a 'red' dot quickly tells aquarists a parameter is out of range (the acceptable range is fully customizable). Click on any parameters to get more information and advice. Watch seneye mobile in action: http://vimeo.com/21218573 What are some benefits of all this monitoring? Constant, accessible monitoring of ammonia, pH, temperature, and water levels can help your tank advert catastrophe (this is speaking from multiple personal experiences, as I'm sure any seasoned aquarist can also attest to). Good light is the key to keeping corals healthy, but do you know where to place your corals or where to mount your lights for optimal distribution? seneye Reef is designed to help answer these questions. Aquarium lights lose intensity over time. Measuring photosynthetic active radiation (PAR) will let you know when they need replacing. The seneye Reef is also ideal for anyone with a planted aquarium; The PAR, LUX and Kelvin light meter is great for ensuring that the plants get the proper amount of light. seneye+ seneye will also offer an optional monthly subscription to a service they call seneye+ ($8 USD, 7 Euro, or £6). seneye+ benefits include: [*]replacement slides (used for NH3 and pH monitoring), delivered to your door each month.**[*]email and SMS alerts. seneye also employs predicative software which can alert subscribers about impending dangerous conditions before they occur.[*]automatic online graphing[*]personalized advice based on analysis of your data[*]access to seneye's knowledge base ** You may wonder why seneye's pH monitor requires replacement slides while other pH monitors do not. The benefit of slides is their simplicity. seneye made the conscious design choice to eliminate the need for calibration - a time-consuming upkeep that is required (but often neglected) by users of electronic pH probes. One of the main design goals of the seneye device is to simplify monitoring/testing for all aquarists (new or experienced), but without jeopardizing accuracy due to user error or neglect. seneye deemed replacement slides as the best (and safest) way to achieve this. I'm tempted to buy the seneye Reef just for the packaging alone Pricing and Availability The retail price for the seneye Reef is not yet finalized but will be approximately $190 in the US, 130 in EU, and £99 in the UK. With a feature set as rich as this, the seneye Reef represents an extremely good value. PAR meters (e.g. Apogee Instruments) usually cost more than this. I'm really quite surprised and impressed by the target price, and if this device works as advertised, this may very well become the hottest new product of the year. While this is a monitor-only device (not a controller), all the functions seneye Reef is capable of makes it a very worthwhile addition to your aquarium, even if you already own a controller. The seneye devices will be available at the end of July, but people can register for the beta program now by going to www.seneye.com. Please visit seneye's website and check back regularly with Advanced Aquarist for the latest information on the seneye Reef. View the full article

If it is melting , it mean that the Bio pallets is working lol . It depend on the bio load of your tank system, the higher it is the faster the bio pallet melts. Maybe you want to consider using a bigger reactor to contain more Bio pallets , so you need not top up so often.

In appearance wise, LED is definitely the best since it give you the same shimming effect like what a MH does without all the heat and high power consumption along with it;s brightness and lux. However , i feel that some of the element like the color light spectrum which the T5 tube can provide to enhance coral growth and coloration is still lacking in some of the LEDs.

Husbandry Series: Selection & Companionability Fish | Coral | Invertebrate The proper selection of invertebrates is critical to achieving a balanced marine ecosystem, and this week the subject of husbandry within your aquarium will focus on invertebrates and how their presence can also help improve the health of your aquarium. There are plenty of aesthetically pleasing crabs, shrimp, snails, and starfish to be found on the market; As with the relationship between fish and coral, the aim is to find invertebrates that are compatible with the existing specimens in the aquarium. Most of the hermit crabs, snails and shrimp sold at your local fish store will typically be referred to as the “clean-up crew”. This term infers a collection of animals that clean your aquarium of dissolved or decaying organics and detritus. "Clean-up crew" critters are mostly foragers and scavengers, leaving the hard work of predation to larger, more formidable organisms. They are very effective "utilitarian" animals and make great additions to your reef. An algae outbreak is one the worst nightmares for hobbyists due to its negative impact on the aesthetic quality and health of your tank. Most snails are purchased for the control of nuisance algae and the consumption of decaying organic matter. Common algae-eating snails include Trochus, Turbo, Margarita, Abalones, and Astrea. The addition of snails such as Nassarius, Nerites, Cerith, and Conches can help control detritus in your reef. Blue Legged Hermit Crab (Clibanarius tricolor). Photo and Hermit Crab article by Richard Aspinall Crabs are a benefit to your tank for the same purposes as snails. Hermit crabs, in particular, are arguably better buys than most snails as they are more active and effective at both algae consumption as well as scavenging. An inexpensive and readily available member of the clean-up-crew, most hermit crabs are communal creatures exhibiting a curious and social nature. There are many species of hermit crabs, some of which are not "reef safe" so take caution when selecting hermit crabs for your marine aquarium. Blue Legged Hermit Crabs (Clibanarius tricolor) and Scarlet Reef Hermit Crab (Paguristes cadenati) are the two most popular "reef safe" hermit crabs and are both very lively additions to the tank. There are a great variety of other crabs available to hobbyists. Like hermit crabs, some crabs are great additions, while others are not "reef safe." Some crabs also have very special requirements, so research carefully Here are two good articles to help you make your selection: Crabs in the Marine Aquarium by James W. Fatherree, M.Sc. Hermit Crabs by Richard Aspinall Cleaner Shrimp (Lysmata amboinensis) next to Micromussa sp coral Shrimps (decapod crustaceans) are also popular additions to reef tanks, and for good reason. Known for the distinct red and white stripes running down its back, the most commonly kept shrimp in the hobby is the Cleaner Shrimp (Lysmata amboinensis). A shy but inquisitive creature, the Cleaner Shrimp will learn to take pieces of food right from your hand. Its natural tendency to remove parasites and other harmful organisms from fish is one of the most notable and beneficial forms of symbiosis found in the hobby today. Another type of shrimp is commonly called the “Peppermint Shrimp” (Lysmata wurdemanni complex and L.boggessi). This ornamental crustacean is distinctly colored with red bands running all over its body and has an almost opaque exoskeleton. They are excellent scavengers natural and their natural ability to consume and control a nuisance form of anemone called Aiptasia sp. qualifies the peppermint shrimp as a great addition to any mixed reef aquarium. Starfish (sometimes referred to as sea stars) can add some aesthetic qualities as well as some very effective forms of cleanup. Most starfish are passive predators, feeding on sessile prey such as mollusks, barnacles and other slow-moving invertebrates. These interesting critters are readily available in the marine aquarium hobby for their association with the clean-up-crew philosophy we discussed earlier. The Brittle Starfish is among the most interestingly looking echinoderms in the world and is in a phylum with over 7000 living species offering a wide variety of shapes and coloration. Fitting just outside the direct definition of starfish, brittle stars have a centralized demarcated body that is clearly separated from their arms. This differentiation and natural flexibility lends them the ability to squeeze into tiny crevices within the rockwork making them very effective foragers. Instead of moving slowly on tube like feet like a true starfish, the Ophiuroidae group of echinoderms can scurry quickly with the movement of these agile arms. Many but not all species of starfish are very effective scavengers capable of excreting their stomach filaments through their mouth to digest their food outside of the body. In extreme cases some species can exhibit higher levels of predation and even can catch slower moving prey. One of the most notorious starfish that is receiving a lot of media coverage right now is the aptly named Crown-of-Thorns Starfish (Acanthaster planci). This echinoderm specializes in consuming all types of coral and may inflict considerable damage to large portions of the coral reef. It is rarely if ever available in the trade but the very nature of this species lends credence to the range of behaviors and diets of many marine dwellers. Craig Bagby's beautiful Tridacna clam nestled in corals. Clams also make great additions to a well-established and well-maintained reef ecosystem. Tridacnids are the most commonly kept species of clams in the reef aquarium hobby, and the diffraction of light across their tissues is absolutely amazing. Containing eight species including Tridacna maxima, T.crocea, T.squamosa, and T.derasa, this family of gastropod includes some of the largest clams in the ocean, with the Tridacna gigas clam reaching up to three feet in length. Clams are a great addition to nutrient rich tanks as they are voracious filter feeders and the all thrive with the presence of symbiotic algae (zooxanthellae) that live within their mantle tissue. Some non-photosynthetic bivalves sold at the local fish stores include Flame Scallops (Lima scabra), as well as oysters and barnacles. Because they lack zooxanthellae, non-photosynthetic bivalves rely solely on filter feeding for energy and are much more difficult to care for. In Summary <h3></h3>Taking the extra time to find compatibility write-ups regarding the proper selection of fish, invertebrates, and coral will vastly increase the overall health and appearance of your tank as well as significantly influence the well-being of each specimen it contains. With the definition of husbandry explained and some key terms presented, hobbyists are now better equipped to make a suitable selection of inhabitants for their marine tank. The proper method of selection will help you allocate funds more effectively by limiting the loss of fish and other animals you purchase. Tune in next week when we discuss the common mistakes newer hobbyists often make, and see how educated purchases can save you money while making the hobby more enjoyable. View the full article

I feel both types of lighting has it pro and cons. But a combination of both High pwer LED together with T5 tube would be the best . Too bad, there isn;t much option on this at the current moment in the market.

i would do that if time allow . This would 100% ensure that all these parasites are gone before adding back the fish.

In conclusion, you might want to consider using these method to control your N03 without doing regular expensive water change; However each method come with the Pros and Cons of it so remember to do more research about it before deciding which is the best method for you. 1) Build a refugium with DSB ( Deep Sand Bed ) together with some algae 2) Using bacteria products like Micro- Lift special blend or AZN03. 3) Use a Algae scrubber 4) Large water change ( This would be the fastest method to bring N03 down ) 5) Reduce your feeding. 6) Bio pallets 7) DeNitrator 8) Dosing vodka

You can just use a simple float valve with a top up tank for the job. Madpetz is selling those as well ;

Check if there is any dead fish or rotting plant in your tank ? Most of the bacteria product in the market will only help to bring down Ammonia and N02 just like your biological filter does, N03 has to be reduce by pseudomonas and clostridium bacterical in an anaerobic conditions into harmless nitrogen gases or consume by algae as a fertilizer . Below is some of the ways you can remove the high N03 in your tank; 1) Build a refugium with DSB ( Deep Sand Bed ) together with some algae 2) Using bacteria products like Micro- Lift special blend or AZN03. 3) Use a Algae scrubber 4) Large water change ( This would be the fastest method to bring N03 down ) 5) Reduce your feeding.

According to AllPetNews The San Francisco Animal Control and Welfare Commission is suggesting a citywide ban on goldfish, guppy, and tropical fish sales in an attempt to prevent “impulse buys,” which many times leads to the animals being left at shelters or dropped off in the wild. A recently proposed bill already targets the sale of small animals such as puppies, kittens, hamsters, and guinea pigs. A few San Francisco officials are now also considering adding tropical fish to the ban list. According to Commission member Philip Gerrie, "Goldfish, guppies and other tropical fish were added to the proposed ban because the ‘inhumane suffering of fish’ and the way the fish are harvested." Gerrie goes on to say, "It causes animal suffering, whole reefs and ecosystems are being exploited for whatever might be marketable or sellable.” As of right now, the bill is not expected to pass. Let's hope it stays that way. View the full article

Scientists from the Instituto Español de Oceanografía (IEO) have once again obtained viable bluefin tuna spawnings in their facilities in Murcia without the need for hormonal induction. A new opportunity to study the way in which this endangered species reproduces in captivity. The researchers are confident that they will achieve far greater results than those obtained over the past two years wherein survival rates of between 73 and 110 days respectively, were obtained.
