Ecotech Marine Announces Radion Gen 4 LED Fixtures – Part 1
The new Ecotech models include the XR30wG4, G4PRO, and XR15wG4PRO and Ecotech expects to begin shipping orders later this month. The Radion G4 features a whole LED new cluster along with a new lens design. The re-balancing of proven colors combined with the addition of warm white and violet takes color rendition for your corals to the next level. Reconfiguration of the clusters compliments the all-new HEI lenses to deliver balanced color mixing better than ever before. The HEI lenses on the G4 deliver more usable light area. This is accomplished by spreading light that would normally create an area of high PAR directly under the LED fixture and redirecting it to a significantly wider optimal area of intensity forReef Threads Podcast #286
One of the coral beauty fish that Kathy Leahy has raised from egg to settle and adult color.
We end our one-week hiatus with a terrific discussion with marine fish breeder Kathy Leahy. In the podcast we talk about fish breeding in general, the recent MBI conference, and, most exciting, Kathy’s success as the first person to raise the coral beauty from eggs to settle. We apologize for the few moments when technology let us down, but are confident you’ll enjoy the discussion. Download the podcast here, or subscribe to our podcasts at iTunes. Also, follow us on Twitter at reefthreads.—Gary and ChristineSponsor: Rod’s Food

Time-lapse Documents Coral Bleaching
For the first time ever researchers from The Queensland University of Technology have documented through time-lapse photography, the event known as coral bleaching. Using a combination of technologies scientists were able to record what they dubbed “pulsed...Jellyfish Watch
With summer ending and school just beginning, Jellyfish season is in high gear. While fishing at the coast this past weekend I noted that the Jellyfish and Sea Nettle populations are well represented. Higher water temperatures bring larger and more concentrated populations of the relatively harmless Cannonball Jellyfish and venomous Atlantic Sea Nettles, Chrysaora quinquecirrha. There have also been reports of box jellyfish (Chiropsalmus quadrumanus) or four handed jellyfish as they are commonly called in the Myrtle Beach area. Fortunately these jellyfish are not as common as our Cannonball Jellyfish but they can be found in the Atlantic Ocean, the Gulf of Mexico and the Pacific Ocean. The sting is venomous and dangerous to humans, especially children. Photo Credit: Jellyfish Watch http://www.jellywatch.org/node/6715Salty Q&A: To Rinse or not to Rinse Frozen Foods?
QuestionThis is probably a silly question, but should I rinse frozen food before feeding it to my fish? I usually just thaw the food in a cup full of aquarium water and pour it right in.” – Submitted by GMan Answer Here at Saltwater Smarts, the only silly question is the one left unasked (well, that and “What can I take to cure my kleptomania?”). Besides, I’m sure plenty of other folks out there are wondering the same thing. As is so often the case with questions pertaining to this hobby of ours, my answer is, “It depends.” Many frozen foods contain a lot of packing juice (you’ll see a cloud of the stuff in the water right after feeding) that will serve only to introduce dissolved nutrients, degrade water quality, and fuel algal blooms. So I will usually strain and rinse them in a fine-mesh net before feeding. Typically I do this over the sink under a stream of RO/DI water, but you can also put the portion in a cup with a little water, wait a few minutes for it to thaw, and then, with the net held over the sink, pour the contents of the cup through the mesh. After rinsing/straining and while the food is still in the net over the sink, I also like to apply a little gentle pressure (not squashing it) to the portion with the back of a spoon in order to squeeze out as much extra fluid as possible.
