Both the billing salt and commercial addictive will rise the salinity over time if you dose to much,so better to check the salinity regularly. Sent from my GT-I9300 using Tapatalk 2

it will kill the aiptasia and as well as the bacteria in the rock but bacteria will start building up again very soon once it is put back into the tank. So far this is one of the effective way i tried that prevent the aiptasia from growing back. There is also some supplement in the market which can control this , maybe someone whom had tried can share . I only tried joe juice before but it doesn't really work since the aiptasia grow back on the same rock again after few week .

Click through to see the images. Here at Advanced Aquarist, we love mimics from fish that mimic flatworms, to mimic octopuses, to fish that mimic mimic octopuses. Blennywatcher.com just reminded me of another mimic I love: Phyllodesmium rudmani, the xenia-mimicing nudibranch. Named after malacologist William B. Rudman, this nudibranch is incredibly hard to tell the difference when comparing it to its prey: Xenia spp. corals. From the top, the only real way is to tell by looking for two white protruding rhinophores, or sensory tentacles that grow out the front of this nudibranch. This nudibranch is really quite amazing as its certa, or outgrowths on its back, look much like pulsing Xenia polyps. One interesting fact is this nudibranch actually contains Symbiodinium spp. zooxanthellae, meaning that it is at least partially photosynthetic relying on its zooxanthellae for at least some of its energy requirements. Normally this nudibranch is found nestled in a hollow in a Xenia colony but they are occasionally seen crawling around on the reef. Currently it is only found in North Sulawesi, Indonesia and Luzon, the Philippines. Blennywatcher.com shot some great video of this nudibranch in the wild: View the full article

I did not keep a blue face before, but i think is due to the morphing when it turn adult from young ?

Click through to see the images. As people know, MACNA 2013 is taking place August 30 - September 1 in sunny Ft. Lauderdale in the posh Westin Diplomat Hotel of Hollywood Florida. The MACNA committee has just let us know that the Westin Diplomat has approved an expansion of the Great Hall conference floor to accomidate an even larger vendor space than initially proposed. This expansion will move the speaker rooms to the Atlantic Ballroom downstairs, which are much larger than the previously scheduled rooms and are easily accessible via escalator from the Great Hall front entrance. Due to the expansion, the floor plan will need revised and finalized once the Fire Marshall approves the plan. The existing layout will not change for paid vendors and will add an additional 50 to 55 vendors to the floor plan. We highly encourage all of our readers to follow MACNA 2013 on their Facebook page to keep up with the latest information and announcements as the months and days slowly count down. This MACNA is shaping up as quite the event and we are looking forward to what is in store for all of us in ten months. Get your tickets now! View the full article

Depending on the height of your tank. Mine is a 2ft height so 50w is ok. If you have a 2.5 ft height go for the 120W Sent from my GT-I9300 using Tapatalk 2

You can already find these commercial addictive from Irwana, Gemsurf and Madpetz from their store. It is already at a very competitive price but without you stocking up alot of these in your store room.

you can try talking to reef systems, they should be able to help you on this.

Large corals corals populate both the foreground and background, with layers of stony coral colonies "sloped" in between; The sum of this aquarist's aquascaping effort is a convincing illusion of depth and perspective.

Better to cycle the AR for a few week before putting in the competition tank on that day. Sent from my GT-I9300 using Tapatalk 2 -
Click through to see the images. Published late last week in the journal PLoS ONE, researchers Orphal Colleye and Eric Parmentier have uncovered why clownfish make sounds in their paper titled "Overview on the Diversity of Sounds Produced by Clownfishes (Pomacentridae): Importance of Acoustic Signals in Their Peculiar Way of Life." Fish are known to make vocalizations and many use them for establishing both social heirarchy and for mate attraction. Clownfish in particular make a lot of vocalizations and Colleye and Parmentier wanted to know to what extent vocalizations played a part in social interactions in the clownfish family (Pomacentridae). What the researchers found was that the sounds produced by clownfish, in this case Tomato clowns (Amphiprion frenatus) were confined to two groupings: aggressive sounds along with threatening behavior (charge and chase), and submissive sounds emitted when fish exhibited head shaking movements (i.e. a submissive posture). The emitted sounds were correlated with fish body size with smaller fish making submissive sounds and larger fish emitting more aggressive sounds. They also noted that no distinction in sound was heard when it came to actual breeding behavior (i.e. attracting a mate). The journal article also contained two short videos documenting the sound characteristics of each dominant / submissive vocalization: Aggressive sounds: note the larger fish is chasing the smaller fish in this video. Submissive sounds: note the fish making sounds while performing lateral quivering that begins at the head The conclusions are important as clownfish maintain a very size-specific social structure.

Natural Product Produced by Marine Algae Shows Promise in Stroke Recovery Treatment A new study using brevetoxin-2, a compound produced naturally by marine algae, stimulated nerve cell growth and plasticity in cultured mouse neurons. This research advances a potentially new pharmacological treatment to aid recovery of brain function following a stroke or other traumatic brain injury. Stroke is a leading cause of death in the United States with more than 795,000 people suffering a stroke each year, according to the Center for Disease Control. Stroke is a leading cause of serious long-term disability and there is currently no drug treatment for post-stroke rehabilitation. "Our research suggests that compounds like brevetoxin-2 can augment neuronal plasticity potentially providing a neural repair therapy for stroke recovery. If that outcome can be supported by further studies in animals and subsequently humans, it could have a profound impact on a currently non-treatable condition," said Thomas F. Murray, Ph.D. associate vice president for Health Science Research and professor and chair of the Department of Pharmacology, Creighton School of Medicine. The research team from Creighton University School of Medicine, University of North Carolina Wilmington, and Scripps Institution of Oceanography published their findings in the Nov. 12 online edition of the journal Proceedings of the National Academy of Sciences (PNAS). The tiny marine dinoflagellate Karenia brevis produces brevetoxin, which in high concentrations is responsible for the harmful algal blooms known as red tides that occur in the waters off the west coast of Florida. The neurotoxin-laden red tide causes respiratory irritation in humans and central nervous system paralysis in fish. "Brevetoxin is a neurotoxin that is known to activate nerves cells to fire spontaneously," said Dan Baden, Ph.D. He is director of the Center for Marine Science as well as a founding member and Executive Principal of MARBIONC at University of North Carolina Wilmington. "It's a great advancement to show that this naturally occurring ocean compound can stimulate nerve cell growth in cultured mouse cells." Brevetoxin is one of more than 1,000 ocean organisms cultured at the University of North Carolina Wilmington's MARBIONC facility (Marine Biotechnology in North Carolina) for use in bio-medical research. The bioactive materials from Karenia brevis have been actively studied by Baden since the early 1970s. A clot that restricts blood flow to an area of the brain causes a stroke. Although the dead tissue cannot be revived, the brain can be trained to redirect nerve impulses to living nerve cells nearby. Recent scientific studies have shown that rewiring of nerve cells following a stroke occurs as a result of heightened plasticity around the brain's damaged cerebral cortex, which is the area of the brain responsible for sensory and cognitive nervous system functions. This new study showed enhanced neuronal sprouting, the growth of axons or dendrites of a nerve cell as well the formation of new synapses between nerve cells in mouse neurons in a culture dish. via Creighton University Journal Reference: J.
