Click through to see the images. Greco Aqualabs C6 stakes its claim as the superior GAC because of its very fine granular size [meaning higher reactive surface area) and greater porosity than other GACs available to hobbyists today. These attributes reportly translates to C6 providing more efficient and greater chemical removal, with the caveat that users will have to use finer micron filter bags or lower flow rates through their media reactors (much like you would with ferric oxide media). C6 removes hydrogen sulfide, chloramine, chlorine, and iron and is free of phosphates. C6 is sold through ReadyAquatics.com (an Advanced Aquarist sponsor). Prices start at $9.99 for 10 ounce and $14.99 for 20 ounce. And I gotta admit, the graduated flask packaging is pretty darn cool! View the full article

Some staff members at Reef HQ speculate that the babies could be clones from an injured jelly that had been housed and died in the tank months before: "Jellyfish clone very easily. When some jellyfish are cut in half, you get two jellyfish," said Reef HQ aquarist Krystal Huff to . "Since the parent jellyfish was injured, it had damaged tissue cells which could have grown into other jellyfish." Others speculate that it could be from an unobserved mating. In any event, the new babies will be a welcome addition to Reef HQ, one of the world's largest living coral reef aquariums. (via Adelaide Now) View the full article

i have some spare shirt left from the last order. Will post the detail here soon.

Bird's nest coral is common throughout the Indo-Pacific and is able to live across a range of depths. New research used genetic and photosynthetic analysis to demonstrate that the genetic differences between both bird's nest corals and their algal symbionts, which provide energy for the corals to survive, reflect adaptations to the different environmental conditions encountered at different depths.

Usually the harlequin shrimp will keep the starfish alive till they eaten the last leg, but still some time i saw my shrimp kill the starfish before eating it up. In order not to pollute my tank too much, i will usually cut one of the leg and let them feed while i kept the starfish inside my refrugium for it to heal back, If you have a few starfish inside your refrugium, you can rotate with different star fish each time. I do observe as well that they tend to feed slower if there is only one leg available for them to feed upon instead of the whole star fish. By following the method above, 2 starfish can usually last my shrimp for about 3 month.

Marine life Still have various Nice size Flame angels, Yellow tang. LCK still have various sizes AT, Grade A picasso , mystery wrasse , and Queen angel ect...

This is one of the worst thing that can happen in reefing. So did you check what is the main cause of your leakage ? Is the leak from the silicon holding the sump give way or ? The live rock inside your main tank would be able to act as your temp biological filtration, and as what Fuel said feed less at this moment until you get a new sump installed. Run a simple air stone in the main stone will help as well, meanwhile you can contact any tank maker to make a new sump for you.

Hi bro, Or you can try rising up the skimmer with a DIY stand ? I did the same for my in sump skimmer. I guess it is common for reefer to experience some "surprises " in this hobby, even through how well planned the setup might be, there will still be a last min changes or alternation, just like my current setup which i have to redo my whole sump tank and piping just to have the "Ideal" setting which i want. Although i still felt my system is still not 100% perfect, but i guess that's every reefer dream to pursuit the perfect system.

Hi, It is alright to placed your Harlequin shrimp in the tank together with your fish unless you are keeping a predatory fish i.e Lion fish

It's not often that we come across these bizarre "piebald" aberrant Zebrasoma sp. in the hobby, and the folks over at LiveAquaria's Diver's Den have this beautiful fish in captivity about to hit the "Divers Den" WYSIWYG section of the site. This beautiful aberrant Hawaiian Yellow Tang (Zebrasoma flavescens) shows an unusual light-yellow color that almost appears to be "glow in the dark" with bright orange and yellow streaks of color near the dorsal and ###### fins. We're told that this fish is going to be sold on the Divers Den sometime this weekend and chances are it won't last very long. If you'd like to take a shot at purchasing it, be sure to sign up for the LiveAquaria E-Mail Alert here so you can be instantly notified when it goes up for grabs. View the full article

In August of 2011, researchers confirmed a bacterium from human excrement, Serratia marcescens, is responsible for White Pox Disease that has devastated Elkhorn Coral (Acropora palmata). Now new research from the University of Florida believes we may be able to employ beneficial bacteria to combat their virulent cousins. Robert Wells of the University of Florida shares his news article with Advanced Aquarist. Beneficial bacteria can help keep Florida coral healthy, UF researchers report GAINESVILLE, Fla. — Bacteria that could potentially help corals resist the devastating disease white pox have been found by researchers at the University of Florida and Mote Marine Laboratory. The findings could help maintain the health of Florida’s coral reefs, which bring in billions of dollars to the state annually and are important for tourism, fisheries, shoreline protection and pharmaceutical research. “Coral reefs are a major attraction for tourists in Florida,” said Max Teplitski, a microbiologist and an associate professor at UF’s Institute of Food and Agricultural Sciences. “They support the economies of South Florida, and they’re also important for fisheries and, in general, healthy ecosystems.” “Unfortunately, in the past 20 years, corals have been degrading due to global environmental changes and direct human impacts, like overfishing and other pressures,” he said. “And also, diseases have been wiping out stressed corals in South Florida.” White pox is caused by Serratia marcescens, a bacterium that commonly occurs in feces of animals and is capable of attacking a variety of animals and plants. To combat white pox, Teplitski and a team of researchers began studying the interactions between the pathogen that causes the malady and other microorganisms that live on corals. Their findings are detailed in a study Teplitski co-authored in this month’s issue of The ISME Journal: Multidisciplinary Journal of Microbial Ecology. Corals are ancient creatures that recruit microorganisms such as bacteria to protect themselves from disease. Their characteristic structure is built by animals known as polyps. In the study, the researchers screened several hundred bacteria isolated from coral and non-coral polyps for the ability to help ward off white pox. The researchers found four bacteria that stopped white pox disease progression under controlled laboratory conditions and, to some degree, protected the polyps from getting sick. They also noted that polyps containing the bacteria survived white pox infection, whereas those without the bacteria died. Based on these results, scientists may begin checking individual polyps for the presence of beneficial bacteria before introducing them into a reef system as part of coral reef restoration. Kim Ritchie, senior scientist and manager for the marine microbiology program at Mote Marine Laboratory in Sarasota, said Florida’s coral reefs are some of the sickest in the world. “They seem to be in the worst shape,” said Ritchie, a co-author of the study. “But the more we can learn about the balance of beneficial bacteria and pathogenic bacteria, the easier it will be to help the coral reefs in the Keys become healthier.” The research was funded by sales of Protect Our Reefs specialty license plates, a statewide program administered by Mote Marine Laboratory Inc. Study authors also include Ali Alagely, a former UF undergraduate student, and Cory Krediet, a doctoral student in the interdisciplinary ecology program at UF’s School of Natural Resources and Environment.

Unfortunately the agent is not bringing in this new salt in yet.

It is quite normal to notice some algae on the rock since most of the corals is from the wild.

You can try getting those "L" bracket in IKEA and fix it inside or beside your sump.

Irwanna new shipment, plenty of nano fish / invert and hard corals..

The tiny phytoplankton Emiliania huxleyi, invisible to the naked eye, plays an outsized role in drawing carbon from the atmosphere and sequestering it deep in the seas. But this role may change as ocean water becomes warmer and more acidic, according to a research team. View the full article

Piranhas are best known for their bite, but did you know they make sounds too? A team of researchers knew that piranhas could produce at least one sound, but they didn't know when and why the fish become vocal. Filming and recording sounds produced by piranhas competing for food, they found that the fearsome fish have a repertoire of three sounds to threaten competitors. View the full article

In less than two years, almost every aquarium had thriving guppy populations ... all from one single female. This is possible because female guppies can store sperm for many months. Dr. Amy Deacon, the lead researcher at St Andrews, says: "Our findings show that the guppy's range has expanded dramatically since the early 1900s. Usually only one or a few fish are released. We know that the vast majority of species introduced to a new habitat in this way are unable to survive, let alone establish a population, which left us with a huge question mark." "Sperm storage is an excellent adaptation for living in constantly changing habitats, and it might also explain the guppies' global success. Female guppies can store sperm in their reproductive tracts for many months after mating, and this enables single fish to establish populations even when no males are present. "We also found that these populations kept all of the important behaviours that wild guppies have, so they would be well-equipped for surviving in a new environment." In many parts of the world, guppies are used as mosquito control because guppies readily consume mosquito larvae which are laid on the surface of static water. However, some guppies find their way into natural waterways due to rains, floods, or people simply disposing of their guppy-filled water into local waters. In many places, these guppies have had a negative impact on native fish faunas. Knowing that a single female guppy can spawn generations of guppies and colonize native waterways, we are once again reminded to practice responsible disposal of our aquarium livestock. Whether it's one cup of sand, a piece of live rock, some unwanted plants, or just one lonely guppy, a single act of negligence can alter ecosystems forever.
