Euroquatics E5 Press Release

Euroquatics has announce the release of their new lamps featuring the E5 LED technology.  These lights can be used in existing T5 fixtures as replacement bulbs for T5 lamps and are much brighter and longer lasting than the predecessor T5 technology.  Euroquatics is providing AquaNerd with some sample lamps for a product review and you can follow our testing on future blog posts.  We will be taking PAR readings with a BioTek Marine PAR sensor and discussing these lamps in detail after they arrive and we begin to check them out. The highly efficient E5 lamps are designed to work in sync with original T5HO fixtures. These unique products showcase features that create an eco-friendly aquarium lamp that lasts up to five times

What are the Odds of Being Attacked by a Shark?

Let’s face it, anyone that has ever stepped foot in the ocean has had that moment where something unexpected touched your body beneath the water resulting in a “you tube” worthy series of epic jumps and arm flailing that put the best ninjas to shame. Most of the time, it’s just a piece of sea weed or an annoying relative, but have you ever really thought about the odds of a shark attack? Well fear no longer! Statistically you are more likely to die from fireworks (1 in 340,733) or from accidental poisoning (1 in 19,456) than a shark attack. Worldwide, there are 70 – 100 shark attacks a year, with only 5 – 15 of those resulting in death. Most of the time, if there is an incident,

Reef Life Support Systems WavePuck

Daniel Nguyen and the guys at Reef Life Support Systems (RLSS) have been working on an exciting new wave maker device known as the WavePuck.  Slightly smaller than a hockey puck, this is the 1st public viewing of the 3D printed prototype.  I first had a sneak peak at the device this past September at MACNA in Washington, DC  but until now I had to keep this information under lockdown until now. Daniel, the owner of RLSS in Canada, has developed a low profile magnetic pivotal wavemaker. At a nominal 1.5″ thick x 3″ footprint, it is now the lowest profile wavemaker device of its kind. Today RLSS announced plans to produce 4 models of the Wave Puck with the 1st model generating a maximum flow rate

Fossil of Massive Marine Crocodile Found on Edge of Sahara Desert

Paleontologists have discovered the fossil remains of the world’s biggest ocean-dwelling crocodile buried on the edge of the Sahara, a creature that was twice the size of anything seen today. Named Machimosaurus rex, this croc would have weighed in at least 6,600 pounds and been around 32 feet long. Other than its size, it would have looked much like a modern day crocodile except for its narrow snout – which was designed to allow it swim in the ocean.

It is twice as big as a present day marine

Plans for underwater ‘Oceanscraper’ Revealed

Indeed, the future of human habitation, whether through choice or catastrophe, is often imagined (in popular culture at least) as being beyond Earth’s orbit. Sub-aquatic living still seems, perversely it could be argued, very alien. Not so for Belgian architect Vincent Callebaut. He has revealed ambitious plans for a series of underwater eco-villages that could house up to 20,000 people each in the future. His Aequorea project imagines entirely self-sufficient, spiraling “oceanscrapers” reaching to the sea floor from mangrove-covered marinas on the surface of the world’s oceans. Jellyfish-like in appearance, each oceanscraper would be constructed using recycled plastics from the misleadingly named “Seventh Continent”, or Great Pacific Garbage Patch (much of the debris here is believed to be in the form of

Drugs We Dump May Be Causing Sex Changes in Fish

A new study found 85% of male smallmouth bass in the Northeast are undergoing a sex change. (AP Photo/Idaho Statesman, Roger Phillips) Male bass are experiencing unwanted sex changes, apparently thanks to the “chemical soups” that pass for waterways in the Northeast. The Washington Post reports 85% of male smallmouth bass surveyed in the region have “characteristics of the opposite sex”—specifically eggs where their testes should be. The same is true of 27% of area largemouth bass, Vice adds. For a recently published study, researchers tested bass near 19 wildlife refuges in the Northeast, according to a US Geological Survey press release. Researchers didn’t do a chemical analysis of the water where the intersex fish were found, so they can’t be sure specifically what is

MaxSpect Responds to News of Suspected Gyre “knockoff”

MaxSpect and their US Distributor Coral Vue have asked AquaNerd to assist them in getting the word out regarding a possible attempt to introduce an unauthorized “knockoff” of their MaxSpect Gyre Series pumps into the North American aquarium products market.  The concern is due to a European release of a new cross flow pump by Jebao identified as the Jecod CP-25 and CP-45 pumps.  MaxSpect has filed a patent application for the Gyre design and is exercising its legal rights to notice any potential entities that the sale and distribution of this new pump in the US market may potentially violate its impending patent rights and make the offender subject to penalties for theft of their intellectual property and legal damages which would include injunctive and

Meet the People Who are Rebuilding the Reefs

From the boat, there’s nothing remarkable about the place — just choppy water and a white mooring ball, a few miles offshore. But once we’re underwater, I can see the rows and rows of PVC trees, suspended above the sand in a grid that stretches away into the distant murk. This is a coral nursery. Each tree bears a ripening crop of a hundred or more pieces of coral. The smallest fragments are pinkie-sized, twirling on their tethers as other divers kick by; the largest hang like many-limbed chandeliers, turning slowly in the current. When I get closer, I can see the individual polyps, the anemone-like creatures that make up each fragmented colony. Nestled in the crenellated openings in their solid skeletons, they
