Giesemann will start shipping seven new German-made T5 bulbs in July, 2014. Giesemann explains that by using a new blend of phosphors, the new Powerchrome bulbs provide more light output, longer life, and better spectral stability during its life. We share Giesemann's press release after the jump.
The AI Hydra TwentySix is essentially a half-sized version of the Hydra FiftyTwo. The new miniaturized LED fixture will feature two of AI's newest 13-LED light puck (totaling 26 LEDs, hence its name) and output 90 watts at maximum setting. The TwentySix will retail for $399, available May 29, 2014.
Design work has commenced for the new Cairns Aquarium and Research Centre, scheduled to open in 2016. We love love LOVE the trend of using public aquariums as platforms for avant-garde architectural masterpieces.
Researchers have today released ground-breaking findings that dismiss the ‘Neutral Theory of Biodiversity’. The theory has dominated biodiversity research for the past decade, and been advocated as a tool for conservation and management efforts.
Maxspect is introducing two different advanced LED lights at Interzoo. The Ethereal is a wirelessly controlled, pendant-style lighting system with an integrated clamp mounting arm. The Glaive is designed in a more traditional "light strip" form factor but with a contemporary and sleek style. The Glaive will come with a built-in infrared remote control.
Inspired by a previous version of this concept, Kelsey Kronmiller decided to build a Super Mario Bros themed aquarium of her own. She shares with us some of the build process of an aquarium any nerd would be proud of.
Coral reefs are perhaps nature's best example of a highly intertwined and co-evolved ecosystem. For example, we all know about the intimate and life-sustaining relationship between coral and their symbiont algae. But a coral's reliance on other organisms begins much earlier than that. The settlement of coral larvae demonstrates an even more remarkable interdependency.
Dana Riddle studies zooxanthallae exposed to varying intensities and colors of LEDs between 365nm (UV-A) and 657nm (red). The collected data sheds light on how different spectra affect photosynthesis and the Xanthophyll Cycle, helping us to better understand how corals use and respond to light.
When Aqua Planet Islan in South Korea opened last month, the public aquarium treated guests to these two amazing 1200 gallon walk-through jellyfish aquariums designed by aquarium fabricator Tenji, Inc. Lots of thought went into making such a radically shaped tank practical for sustaining jellyfish.
Smithsonian scientists describe a colorful new species of small coral reef sea bass from depths of 182–241 m off Curaçao, southern Caribbean. With predominantly yellow body and fins, the new species, Liopropoma santi, closely resembles the other two "golden basses" found together with it at Curaçao: L. aberrans and L. olneyi.
It's always enlightening to see what our hobby is like in other parts of the world, but sometimes cultural or language barriers make it difficult to understand and relate. Matt Galat is an American expat working - and reefkeeping - in Ningbo, China. He's started a video series showing Western aquarists what it's like to keep reef tanks in China.
The MACNA 2014 Board of Directors has just announced that Dr. Rocha will be the keynote speaker for the Saturday night banquet. MACNA 2014 will be in Denver Colorado August 29-13.
We often hear reefkeepers say fish poop is the best coral food, and scientific studies confirm the importance of fish (and fish waste) for coral nutrition. A new UGA study supports the importance or fish for balancing nutrients in coral reefs. Fish not only contribute nutrients but also help maintain a 20:1 nitrogen to phosphorus ratio.
Participating in freshwater aquarium communities, there are three truths we've learned. People love cories, plecos, and are cray cray for crayfish. A new tiny Gramastacus sp. crayfish was discovered in a most unlikely place: a tropical swamp at New South Wales, one of Australia's most developed areas.
Dana takes a detailed look at Tunze Turbelle Stream pumps from a more useful velocity metric instead of the ubiquitous gallons-per-hour metric our hobby has become accustomed to. Water velocity may be the key to certain corals' success.
