JBJ USA is making the most of their booth space at SuperZoo in Las Vegas by introducing a whole slew of new products. They’ve already shown off their new RL-20 Frag Tank, we’ve been told about a new feeder (more to come on that later), we’ve spied a large rimless aquarium (again, more on that later), and now they’re teasing us with a brand new pendant style LED fixture. This powerful LED comes in two different sizes, a 150 and 50 watt model, and will have a color temperature range of 16000 to 20000 Kelvin. Each fixture will include a lens and diode arrangement that has been designed by the folks at Edison-Opto specifically for aquarium use, though you won’t see many of these lights over your average mixed reef aquarium. Instead, the focus for this light will be on aquaculture facilities, public aquarium exhibits, and the largest of private reef aquariums. The standard lens on the new JBJ LED is 100 degrees, but is focused down to 60 degrees when the optional reflector is used. The light can penetrate water depths up to 12 feet, while providing a sufficient amount of light for corals down to about 4 feet. PAR readings taken at various depths seem quite promising, with the 50w fixture hitting a reading 110 PPFD at three feet and the 150w model hitting 270 at the same depth. JBJ promises more technical specs to come soon, and it’s likely that the light will become available in the next 2-3 months. by Robert Loren | Jun 7, 2013 | Corals, DIY, Equipment, Fish, Science, Tanks
The majority of us know at least one fellow reefer who swears by dosing his/her reef aquarium with vodka. This seemingly counterintuitive act is often believed to have beneficial effects on the overall health and appearance of one’s reef aquarium.… by Josh Saul | Jun 7, 2013 | Equipment

For this week’s AquaNerd Picture of the Week, we’re revisiting Daniel Leija’s 40-gallon mixed reef aquarium, which houses one very beautiful Maxi Mini carpet anemones. Carpet anemones have always been a favorite among aquarium keepers, but they are far too large to house in smaller aquaria. So, it’s no surprise that the Maxi Mini anemones are so popular with the small tank crowd. These anemones often exhibit a rainbow of colors, often outlined with a green ring. Despite their name, these anemones can get quite large. While most are sold in the 1-2″ diameter range, they can grow to be 4+” across. « Previous post

Here is a 250-gallon (950-L) reef aquarium owned by Greg Heifner in Colombia, Missouri. The system operates with a 150-gallon algal turf scrubber located below in the basement. Note the profusion of red mushroom anemones on the right-hand-side of the aquascape. From his YouTube posting: 250 gallon reef lit with 560 1-watt LEDs. Algae turf scrubbing system.The tank was lit for years with 900 watts of MH and 80 watts of Actinic florescent. My refrigeration (chiller) unit hardly ever comes on anymore with the cooler LEDs.Half are 12,000K white ones and the others are about 450nm blue.I like these LEDs enough that I am now importing them for other reefkeepers in my community.
