My "Reef Friendly" Quarantine System

I haven’t been involved in this hobby very long compared to other folks but learned very quickly how much of a pain it can be to eradicate, or try to eradicate pests such as Aiptasia, Majanos, Bubble Algae, zoa eating asterinas, and Marine Ich. When I started, I did what I’m sure all of us have done at one time or another: just drop things in the tank and hope for the best. I recently upgraded from a 70g to a 260g tank and decided never again! Unfortunately, everything I found online regarding QT setups mainly dealt with fish only setups, bare bones systems, or that were more of a temporary solution. I’ve had to treat fish in smaller systems I had setup twice for Marine Ich and went through the hyposalinity treatments using a bare bottom tank, HOB filter, and a couple of pieces of PVC

Details Leak on JBJ USA’s Unibody 108 LED Fixture

 At the beginning of the year, an image was posted on the JBJ USA Facebook page that showed three different sizes of the popular Unibody LED fixture. At the time of the image’s release, only the Unibody 54 was available to purchase, though the Unibody 108 and Unibody 36 both appeared to be close to production. Unfortunately, those other two models weren’t quite ready for store shelves when they were first revealed, but the good news is we have just found out that they 108 is currently being tested and its release is imminent. Along with that, we’ve also found out some of the finer details. According to sources at JBJ, the Unibody 108 will have basically the same configuration of the 54 watt model, though it will be double in size. The 108 will have the same 3watt Edison LEDs, which will come in royal blue, blue, and 10000K, though now there will be 36 of them. Each of the colors will be on a separate dimmable channel, totaling three channels overall. This will be the higher end LED fixture in the JBJ USA lineup, and we’re told that it will be offered with wireless capabilities and in a budget friendly option. No word on price or final availability quite yet. More: Details Leak on JBJ USA’s Unibody 108 LED Fixture

Mr. Saltwater Tank’s 225 Gallon VIP Tank 1 Year Update

Two New Species of Coral Discovered in Unlikely Places

Two new Species of Encrusting Anemones (Neozoanthus sp.) has been discovered in a very unexpected ocean. Previously limited to Indian Ocean Water Neozoanthus sp. was thought to only exist in one particular location. However Associate Professor James Davis Reimer and his team located the same species off the coast of Southern Japan and on the Great Barrier Reef of Australia. Photo courtesy of sciencedaily.com The study formally categorizes them as two separate and new species. Reimer was “very surprised in 2008 to discover Neozoanthus in the Pacific, in Japan,” but goes on to say: “These findings can be explained by the fact that there are very few zoanthid researchers in the world. These species are not particularly hard to find, but there was no one looking for them. This research demonstrates how little we know about marine biodiversity, even in regions relatively well researched.” Read more here!

Extreme low tide at Coconut Island

Porites compressa on the reef flat sitting high high and fry during an extreme low tide.

 The Hawai’i Institute of Marine Biology (where I perform much of my research as a graduate student) is located on Coconut Island–or Moku o Loe, in the Hawaiian–in Kāne’ohe Bay on the island of O’ahu, HI. The island is surrounded by a wonderful fringing reef with a well developed reef flat. A major feature of the oceans is the tidal cycle. The tides are driven primarily by the gravity of the moon, and secondarily by the gravity of the sun. When the gravity of the moon and the sun pull on the ocean at approximately a right angle to each other we get the so-called neap tides, which have the smallest tidal range (the difference between high tide and low tide) for the month. We get neap tides around during the first quarter and the third quarter of the lunar cycle (i.e., twice per month). When the gravity of the moon and sun pull Continue reading

How to take a picture of your aquarium: photography course part I

 During my visit to the eighth edition of Salento Aquarium, a show in Italy, I did a lesson on a subject that I really like “Aquarium, how to take pictures“, and are therefore here, as promised, to propose a mini-course as a guideline how to photograph in the aquarium, getting the best with our equipment, obviously the course is open to all, since most of what is written applies to any photographic genre, even though the examples will focus on the photographs in the aquarium. I hope that the course will be useful and that you enjoy reading it, and if you have any requests please leave your comments. This is the first part that covers the basics of photography, the choice of lenses and the setting of the camera, the second part will address specifically the photographs in the aquarium, going into the details of how to photograph aquariums, fish and corals , and the last part will cover instead the development of the digital negative, the RAW file.  Continue reading

It’s the Pretty Skirts

Yes, the intense color is impressive but it’s the skirts that add an extra element of interest.

 Zoanthids and Palythoas are not corals that I keep. It’s not that I don’t like them; they simply don’t excite me. How I came to have a colony of Nuclear Green Palys has slipped from my memory, but I enjoy them nonetheless.
I’ve not always had success bringing out their vibrant green color. This time I got close. But it’s a new discovery that gets me excited about this image. Because my “focus” has always been on the intense green color and making that stand out in the image, I had not paid much attention to the “skirt” tentacles. Wow! They’re really attractive! They also do an excellent job of framing and visually containing the vibrant green. Continue reading
