port royal 5 Must See UnderWater Cities

Port Royal, Jamaica

 Underwater cities are the stuff of legends, dreams and childhood fantasies. Check out these amazing 5 under water civilizations. Archaeologists are still finding artifacts and new information to this date. Port Royal, Jamaica makes number one on the list. It was a lively port, often referred to as the ‘wickedest city on earth’, until a massive earthquake hit Jamaica in 1692. The city had only existed for 37 years, and was underwater in a matter of minutes. The city is amazingly preserved, including villages, hospitals and dockyards. MORE

The Many Means of Nutrient Export in Marine Aquariums

aquarium nutrient export 300x169 The Many Means of Nutrient Export in Marine AquariumsDissolved nutrients. Sounds like a good thing, right? After all, every organism needs nutrients in one form or another in order to grow and stay in good health. So why are marine aquarium hobbyists—particularly reefkeepers—seemingly so fixated on keeping the level of dissolved nutrients in their systems as low as possible? To understand this fixation, you have to keep in mind that the waters surrounding coral reefs are naturally nutrient-poor environments. Unless a reef is subject to agricultural runoff, sewage discharge, etc., the levels of dissolved nutrients around it never approximate what can accumulate in the closed system of a marine aquarium. Elevated dissolved-nutrient levels lead to problems with nuisance algae and declining water quality, which is stressful or even deadly to marine livestock. That’s why hobbyists must implement different measures to export dissolved nutrients from their systems. Here’s a sampling of basic nutrient-export techniques: The routine water change I’ve listed the water change first because it’s the most straightforward technique and provides many additional benefits beyond exporting dissolved nutrients. You should be changing a minimum of 10 percent every week or 20 percent biweekly (more if testing shows that nitrate, and/or phosphate is exceeding the acceptable level), siphoning out as much accumulated particulate waste as possible in the process.

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
