Dream Trip for Two to Fiji Offered at MACNA 2014

2a79MACNA Trip to Fiji Dream Trip for Two to Fiji Offered at MACNA 2014
Raffles are always a big ticket item (see what we did there) at aquarium shows both large and small. Regardless of the speaker lineup, the number of vendors, or the size of the show, there’s nothing that draws a larger crowd than a robust raffle full of awesome prizes. MACNA falls right in line with the rest of the aquarium hobbyist shows when it comes to raffles, usually having a massive amount of items available to the thousands of guests in attendance. But this year they are stepping their game way up. In addition to equipment, frags, and gift cards that are commonplace, the show will also feature a free trip to Fiji. But that’s not all. The all expense paid trip will be hosted by the legendary Walt Smith and his wife Deborah. The trip is 10 days long and features round trip airfare for two from LAX to Fiji, as well as hotel and meal accommodations, free diving on the Walt Smith International (WSI) coral farm, a trip to the WSI export facility, a poolside dinner with Walt and Deborah, and free passes to several local attractions (zipline, waterfalls, and a safari). This raffle giveaway is only available to attendees of the MACNA 2014 banquet dinner, with the drawing most likely happening sometime between the opening speeches and the keynote MORE: Dream Trip for Two to Fiji Offered at MACNA 2014

ATI Finally Goes Full Fledged LED with New Sirius X Fixture

502cATI Srius X LED Fixture ATI Finally Goes Full Fledged LED with New Sirius X Fixture ATI Aquaristik is no stranger to aquarium illumination. For many years, their Powermodule T5HO fixtures have topped the wishlists of many a hobbyist. But over the last few years, T5HO lighting has waned in popularity, giving way to LEDs. ATI seemed to have reisted the trend, as they slowly adopted LEDs into their lineup and only initially as supplemental lighting in their Powermodule hybrids. But, the times seem to be a changin’ and it appears that ATI is finally coming fully on board with LED technology as their latest light fixture sports nothing but tiny little emitter goodness. The ATI Sirius X LED fixtures sport an array of LED clusters, with each pulling about 75watts. The clusters are composed of 13 LEDs each, with the embedded colors being six Cree XPE Blue, two Luxeon M Royal Blue 450nm, two Luxeon M Cool White, two Cree XPE Red 620nm, and one Semileds Violet 420nm. This grouping of LEDs is further broken down into four independently controllable color channels, and to further play to our contol freak needs, the individual clusters themselves are independently programmable from others in the fixture MORE: ATI Finally Goes Full Fledged LED with New Sirius X Fixture

What eats a Great White Shark at 2000 Feet?!

 Great White’s are amazing apex predators. I have been following the research and development of the tagged Great White’s with interest. Recently, some intriguing information regarding ‘shark alpha’ has come to light. A beach goer found the tag belonging to ‘shark alpha’, a healthy 9 foot specimen, washed ashore. The tag revealed some fascinating information. Four months after being tagged, the shark tag revealed temperatures and depths that could only mean the shark would eaten by another predator. The question is what could possibly eat such a large shark? Scientists don’t have any conclusive answers at this time. MORE

How Fast Do Sea Sponges Filter Water?

A while back there was a fair amount of chatter spreading throughout the interwebs regarding the use of sponges as a main, or alternative filtration source. Steve Tyree was one of the first to document and test these methods, dubbing his method a Trizonal Cryptic filter. This method actually used several baffles [within a sump/refugium] containing holes within them, starting with larger holes on the initial baffle, ending in smaller holes in the final baffle, which would filter out particles by size throughout the three sections allowing various species of sponges to feed on their ideal particle size. Steve tested this method from 1995-1999 and wrote his book on the method from 1999-2000, more info can be found on Reef Farmers website and on Reef Central. People started trying various versions of the Trizonal Cryptic system, me included, but I always really wondered how much water can sponges actually filter?

 Recently Jonathan Bird, of Jonathon Bird’s Blue World, posted a video of him squirting a non-toxic fluorescent dye around the base of various sponges in the Caribbean. I was amazed at just how quickly the sponge pulled the dye through the base of the sponge and out the top. Of course, only water [and dye] are making their way through the sponge, while everything else is filtered and utilized by the sponge to grow and reproduce. Here’s the video of Jonathan squirting the dye, and a little history on sponges in general. The fun part starts around 5:30 in the video. MORE
