Researchers have zeroed in on the controversial, non-therapeutic use of antibiotics in food animals and fish farming as a cause of antibiotic resistance in people. There is overwhelming evidence that this overuse of antibiotics affects the environment and humans and they advocate for stricter regulation of the practice. View the full article

If it is the impeller you should be able to find the replacement parts from the distributor, but if it is the pump body most likely you cant find repair since it would likely cost more to send oversea for repair than to buy a new one. Hope it helps

Sexually mature L.amboinensis have both male and female reproductive organs but can not self-fertilize, so they must pair up with another shrimp to reproduce. Anyone looking to breed cleaner shrimps - or regularly spawn shrimp larvae to serve as natural zooplankton for their corals/fish - only needs to place two shrimps together in the same tank. However, if you place more than two cleaner shrimps in the same tank, the situation gets ugly. Researcher Janine Wong and Professor Nico Michiels (University of Tubingen) placed cleaner shrimps in multiple groups of two, three or four in separate tanks. Within 42 days, all tanks only had a pair of shrimps still alive. The dominant pair simply killed off the other shrimps in their tank. The researchers hypothesize this aggression is motivated by reducing competition for clients (and subsequently food source) around their cleaning stations. All subjects in this experiment were provided ample food, so the results suggest cleaner shrimps are "hard-wired" to behave this way. Their research, "Control of social monogamy through aggression in a hermaphroditic shrimp," is published in the scientific journal Frontiers of Zoology. The paper's abstract states: Exactly one individual in each triplet and exactly two individuals in each quartet were killed in aggressive interactions, resulting in group sizes of two individuals. All killed individuals had just moulted. No mortality occurred in single and pair treatments. The number of moults in the surviving shrimp increased significantly after changing from triplets and quartets to pairs. So for anyone considering buying more than two cleaner shrimps for their aquarium, please reconsider; You will still end up with just a pair. An interesting side-fact about Lysmata amboinensis: Cleaner shrimps can only assume the female role a few hours after molting, while they can assume the male role at any time, even when incubating eggs.

Published recently in PLoS ONE, researchers Thomas Adam, Russel Schmitt, and others found an interesting case when evaluating severely damaged coral reefs in the South Pacific in French Polynesia. The reefs fully recovered after being nearly destroyed by predators like the crown-of-thorns starfish or from cyclones. They wondered why this occurred as normally when a reef is decimated by similar forces (especially in the Caribbean), the affected reefs never really bounce back and remain heavily algal-covered. What Adam and the other researchers found was that when these reefs in French Polynesia were destroyed, the herbivorous fish population exploded shortly thereafter. When surveying the surrounding fringing reefs, they found their answer. The fringing reefs were the nursery grounds for many of local populations of fish, most notably surgeonfishes and parrotfishes which are herbivores. The heavy herbivore population helped keep the algal cover to a minimum which in turn helped the remaining coral recover. "We discovered that these fringing reefs act as a nursery ground for baby fishes, most notably herbivorous fishes," said Andrew Brooks, co-author of the paper. "With more food available in the form of algae, the survivorship of these baby parrotfishes and surgeonfishes increased, providing more individuals to help control the algae on the fore reef. In effect, the large numbers of parrotfishes and surgeonfishes are acting like thousands of fishy lawnmowers, keeping the algae cropped down to levels low enough that there is still space for new baby corals to settle onto the reef and begin to grow." This stands in stark contrast to the Caribbean where over-fishing has heavily impacted the herbivorous fish population. With low numbers of adult herbivores, Caribbean reefs struggle to recover. This research should also be highly interesting to managers of Marine Protected Areas as well. Their findings indicate that not only is it important to protect the reefs in general but also the fringing reefs that act as nurseries for the local fish population. "Our new and very novel results suggest that it also is vital to protect the fringing reefs that serve as nursery grounds. Without these nursery grounds, populations of parrotfishes and surgeonfishes can't respond to increasing amounts of algae on the reefs by outputting more baby herbivores."

You can find parazi from our sponsor Aquafauna or Irwanna. Unfortunately there is no test kit to test if the water is free of diseases. Doing a major water change or using Ozone / UV may cut short the process but still it is best to leave the system fish-less for about 4 ~ 6 week so that the ich will die by itself without a host.

Apart from lighting, Perhaps protein skimmers is probably the most important pcs of equipment in a marine / reef aquarium. A protein skimmer is a form of mechanical filtration equipment which is design to remove dissolved organics from the aquarium water.To accomplish this, very small bubbles are being generated inside the skimmer body, and dissolved organics are attracted to the bubbles and rise up to a collectioncup for removal. The waste is usually called skimmate. Most of the dissolved organics inside our aquarium areamphipathic or amphiphilic, which one part of the molecule is attracted towater ( Hydrophilic ) and the other is repelled by water ( Hydrophobic ). These properties cause the water molecules to be attracted to the surface where theair and water meet. This usually occur at the surface of the aquarium but by using a skimmer as part of the aquarium filtration systems, it will helps to remove these dissolved organics / reduce nutrient levels and improve overall water quality in the system. Protein skimmer selection and maintenance - Select the correct types of skimmer for your aquarium. For example if you do not have a sump, never buy a skimmer which is mean for use in a sump. Choose hand on skimmer/ external skimmer or in tank skimmer instead. - Do your homework to check what is the best skimmer which is within your budget. There are many price range skimmer which will suit your budget and requirement. Try to check for product review or ask around in the forum. - Before a skimmer "Kick in", the new skimmer don't usually produce a lot of skimmate during the first few day or so. Or sometimes, they foam like crazy and filling the collection cup with only clear liquid.To tickle this problem, rinse the skimmer with lukewarm to hot water to removethe residual oil from the manufacturing process. - Clean your skimmer collection cup at least onceper week to ensure the skimmer is working at it's best. Try to do a major maintenance of your skimmer but taking out the impellers and washing it with fresh water, and you will be amaze by the different. - Try to buy a size larger skimmer that is ratedfor your tank volume of water. This will help in case if you decide to stock more fish /corals in your tank in futurerather than upgrading it later. However, don't buy too big a size skimmer whichwill take up space and electricity. - If your skimmer is a in sump version, do keep the water level constant at all time as this will affect the skimming performance. In conclusion, the decision of what type of skimmer to buy should always be taken into consideration before building your tank or yoursump as it determine the space required , and the water level in the sump which meet the minimum water requirement for in-sump version.

Wow.. it look so cruel to me.

Each Air Swimmer measures 57 inches long by 36 inches high and is controllable up to 40 feet away with a supplied hand held radio controller. Four AAA batteries are required: three for the RC controller and one for the balloon controller. Units are fully controllable; they have the ability to go up, down, and in a 360 degree circle using an integrated tail fin that gives the balloon a life-like swimming motion. The balloons are made out of durable nylon material and can be refilled with helium at your local florist, party store, or grocery store that has helium refill tanks. Refilled balloons last for weeks on a single charge. One caveat is that Air Swimmers cannot be used outside as the units require still air to operate effectively. With Christmas coming up, these would make excellent gifts for any reef aquarist. They are currently on sale for $39.90 per balloon or $77.28 for the pair. View the full article

Nowadays, the easily way for nutrient export is carbon dosing using Bio pallets . Alternatively you may also consider running a Zeovit system ( Which will remove both N03 and P04 as well) , but both Method require a good skimmer. You can do a research on both.

In Mr. Saltwater Tank's coverage of MACNA 2011 uploaded earlier this week, Mark Callahan interviews a Saudi Arabian reefkeeper who made the trek all the way out to Des Moise, IA to attend the event! The interviewee describes his difficulties acquiring corals in Saudi Arabia due to government restrictions; He mentions having to import corals from neighboring countries like Kuwait. If this video of a Kuwaiti reef display is any indication, he has access to some outstanding corals. The SPS in this tank exhibit some interesting growth forms presumably due to the lower-than-usual flow rates observed in the video. Unfortunately, not much information is available about this display. The tank appears to be maintained at a LFS ... a very fine LFS indeed. View the full article
