  1. Chasing Coral opens eyes, by documenting coral bleaching

    As reef keepers, we know precisely what causes bleaching. Within coral tissue lives photosynthetic zooxanthella algae. To maintain coral health, a delicate balance must be maintained, ensuring the zooxanthella don’t grow too quickly, but that they can always photosynthesize and provide the coral with any additional nutrition.
  2. Yes, Reef Aquariums inspire action.

    Lauren grew up about two hours from where I did, in what is still considered Western Maryland. Both of us lived far from a seashore and made yearly family trips to the Outer Banks of North Carolina. The Outer Banks is a rich seaside community with a diverse abundance of oceanic life. Much of that life is highlighted at the Outer Banks Aquarium in Kill Devil Hills. Lauren was always interested in marine life, from catching crabs on the sand as a little girl, to studying my aquarium when she...
  3. 2017 The Year Of The Critical Thinking Reef Keeper

    Every year, more and more products enter the reef keeping world, aimed at making aquarists believe that simply by adding the directed dose, they will achieve a measure of success. Some claim to clear up nitrate problems, while others claim to balance water quality and maintain aquatic homeostasis. Each year, my email inbox gets filled with messages from aquarists who feel cheated. They’ve spent hundreds (if not thousands) of dollars on reef keeping products believing each one to be the...
  4. Euthanasia - is it morally sound?

    It's likely as aquarists we will encounter a fish that is sick and suffering. Do fish deserve the same dignity other pets are afforded? What must be taken into consideration, when determining if a fish is a candidate for euthanasia.
  5. The current state of nano-aquaria

    It’s been a number of years since JBJ released the original nano-cube. When first released, many aquarists scoffed at the idea of a small, all-in-one marine aquarium. Yet, the idea surged in popularity and now nearly every major aquarium producer has their own version of JBJ’s original design. Now, they are even marketed and sold to beginners and many aquarists become addicted to the hobby via a 12-gallon box of water.
  6. To jellyfish or not to jellyfish, that is the question?

    Like any pet, jellyfish keeping is an expense and responsibility. Luckily the jellyfish offered (usually moon jellyfish) with most packages are captive bred and raised, meaning that the jellyfish fad shouldn’t affect wild ecosystems. The package I purchased had adequate filtration, with an area for carbon media, live rock rubble and mechanical filtration floss. A small pump (like what is found on desktop fountains) moved water around the circular tank, creating the gyre current and pushing...
  7. A new generation of aquarists

    It’s these interactions that seemingly fascinate children and also show them the importance of care and consideration, when intermingling with oceanic life. You can’t just grab any reef dweller indiscriminately and even those that can be handled need compassion and restraint. For children, a clump of macro-algae is its own little world, full of unique creatures just waiting to be discovered. I leave some live rock in my sump, so that it can become engulfed in tiny brittle starfish, snails...
  8. Can feeding alone make corals more adaptable?

    Researchers found that feeding gives the corals a backup way to build caloric energy. The nutrition provided during feeding goes directly to the coral colony and isn’t simply passed on by zooxanthellae. This energy can be directly put to use in building the skeleton and maintaining healthy tissue. It may also be able to aid the coral in mitigating the effects of higher nutrients and perhaps the coral can maintain vitality, even when zooxanthellae are growing faster than usual. For corals,...
  9. Lessons from the Eco Aqualizer

    The story of this product is filled with frivolous lawsuits, strange promises and advertising in some of the largest fish-keeping publications at the time. From the late nineties up until 2006, the Eco Aqualizer made its rounds throughout the world of both marine and freshwater aquaria. Hundreds of reef keepers fell under the Aqualizer’s spell; the promise of complete water filtration in one small, cylindrical device that was easy to install and even easier to conceal.
  10. A step back, a step forward: Kalkwasser dosing

    In this regard, the old way may not only be safer but also more efficient. This involves the use of a kalkwasser stirrer. These are a simple reactor with a water inlet at the bottom and a water outlet at the top. Running vertically through the reactor is a shaft connected to a stirrer. The stirrer can be as simple as horizontal PVC piping or as complex as a series of fins that slowly spin. The shaft and stirrer are connected to an external motor, that spins them either constantly or at...
  11. The Ice Cap Smart RODI: The highest tech RODI unit ever?

    I would be willing to argue that Ice Cap’s Smart RODI is the most technologically advanced unit available to average aquarists. RODI technology hasn’t leaped this far forward in a long time and Ice Cap’s innovations could easily evolve into RODI units that connect to our phones via wi-fi, giving aquarists the ability to make pure water on the go. Yes, we’ve gotten in-line TDS monitoring, filter replacement reminders and even some electronic performance monitoring. The smart RODI takes it...
  12. Is AquaForest the next evolution of zeolite use?

    For any zeovit user looking into AquaForest, I can confidently say that AquaForest’s zeolite inclusive methodology is not zeovit. I don’t mean that in a negative way, but simply to point out that other than relying on a similar mineral and bacteria, the two are very different. Zeovit is a very hands-on approach to reef keeping that requires daily maintenance of the filtration media and consistent dosing. AquaForest’s method also requires dosing and maintenance, but has been simplified to...
  13. Joe Yaiullo awarded MASNA's Aquarist of the Year 2016

    While Joe is most certainly a celebrity in the world of reef aquaria, he remains humble and approachable, consistently offering advice to fellow hobbyists and sharing his aquatic discoveries with the reefing community.
  14. Newly discovered marine fish species to be named after President Obama

    The process of declaring a new fish species isn’t as simple as the outlook of one, or even a team of marine biologists. It will take time, DNA tests and a close inspection of the fish’s physical details and physiology before a formal scientific name is applied. Considering the fish is of the genus Tosanoides (a species previously thought to only occur around Japan) it’s likely the final name will be Tosanoides obama or some variant of that.
  15. Are LEDs a suitable primary light source?

    However, determining if LEDs alone are viable sources of light, requires a better assessment. It’s certainly true that using multiple fixtures creates acceptable PAR readings throughout even a large reef aquarium. However, it’s tough to get totally accurate PAR readings from every nook and cranny within the tank.
