Elos Water Test kit: KH alkalinity

2014 03 elos test kit carbonati dkh 002 Elos Water Test kit: KH alkalinity
I started talking about Elos test kits in 2007, and have been replacing them as I do every 6 months, I’d like to give you an overview of my experiences. Let’s start with the Elos Alkalinity test, or KH.

  As you can see from the photo, the test kit consists of a good-sized box that contains the folding paper with explanations, the leaflet, one glass tube with Elos symbol and its plastic cap, a small bottle containing the liquid reagent called KH and a syringe.  MORE

Video: Satellite Sees Portents Of Powerful El Niño


In 1997-98 the strongest El Nino event on record to date caused unprecedented coral bleaching and death across the globe. Now, in a worrying development, the NASA/French Space Agency Jason-2 satellite has detected tell-tale ‘kelvin waves’ crossing the Pacific that suggest another powerful event may be brewing.

Return from Lubang

Lubang1 Return from LubangWell, we’ve just returned from Lubang Island, and I’ve never been to a more remote, more rustic place in the world. The boat ride we were told would take three hours ended up taking five, but the sea was calm and we had a beautiful ride out. We saw dolphins, jellies, and tons of flying fish. When we first pulled up at the port, there were probably 50 people who came out to look at us. I have no doubt we were the first Americans many of them had seen—kids were yelling, “Power boat! Look, a power boat!” and running over to check out our relatively modest, 15-foot whaler-type boat. As soon as we arrived, four of us took off in the power boat to scout for the dive locations for the next two days. We looked for rocky outcrops on the end of the island facing the drop-off into the South China Sea, and we used side-scan sonar to find rocky areas in the 200- to 350-foot-deep range. After a few stops, we found a spot to dive, so Elliott and I suited up and dropped into a dive site we named “The End of the World.” We did a (relatively) quick pass on the site—buzzing down to 300 feet on scooters and then taking our time coming back up—the total length of dive was 71 minutes, which is about as quick as you can do a dive like MORE: Return from Lubang

New Dosing Pump Module Teased by Digital Aquatics

1fe0Digital Aquatics Dosing Pump New Dosing Pump Module Teased by Digital Aquatics
We’re full of teaser information today, it seems. Digital Aquatics let it slip that they will soon be releasing their very own dosing pump module, called the DP1. This new module is pretty straightforward, using a peristaltic pump to move liquids from one container to another and connecting to the Reef Keeper controller via the BUS connection. A total of 16 individual DP1 modules can be used simultaneously on the RK Elite controller, which is overkill, but it gives users tons of options for dosing various products. As far as mounting the module goes, a pair of screw holes flank the DP1, allowing it to be mounted to the inside of the stand or anywhere else you might want it installed. Pricing for the new module hasn’t been finalized, but we’re told that it will definitely be under $100. In addition to the DP1, another one of the Digital Aquatics modules is getting a refresher MORE: New Dosing Pump Module Teased by Digital Aquatics

Tinker’s Butterflyfish: Beautiful, Hardy, and Way Beyond My Wages

tinkers butterflyfish 300x169 Tinker’s Butterflyfish: Beautiful, Hardy, and Way Beyond My WagesNovice marine aquarium hobbyists—especially those making the transition from freshwater to saltwater fishkeeping—commonly experience “sticker shock” when they see the prices of many marine species offered in the trade. After all, when you’re accustomed to spending only a few dollars to a few tens of dollars for freshwater fishes, even the least expensive marine fish can seem costly by comparison. But some marine species take this price thing to a whole new level, with single specimens fetching many hundreds of dollars—you know, the kind of price that has us average mortal hobbyists thinking, “Hmm, someone must have misplaced a decimal point here.” Among these sticker-shock species is Tinker’s butterflyfish, also known as the Hawaiian butterflyfish (Chaetodon tinkeri), a Pacific butterfly that is most common around the Hawaiian Islands but whose range, according to FishBase, also includes Johnston Island and the Marshall Islands. How much and why so expensive? So what sort of price tag are we talking here? Think somewhere in the vicinity of $500 for a single small specimen. Of course, you can double that for the pairs that are sometimes offered for sale. This exorbitant price can be attributed primarily to the depth at which C. tinkeri is found—again according to FishBase, ranging from 27 to 135 meters (approximately 90 to 450 feet).

Kessil Unveils Spectral Controller for A360 LED Fixtures

1d7eKessil Spectral Controller Kessil Unveils Spectral Controller for A360 LED Fixtures Kessil is making headlines today with the recent announcement of their very own controller, called the Spectral Controller. This new device, which is said to be the size of a smartphone, is designed to work specifically with the Kessil A360 LED light and all future releases. It has the ability to control up to two different sets of lights via two separate 0-10V output ports, but don’t translate that as just two different lights. Instead, the Spectral Controller can program multiple lights spread across two separate “groups”. A prime example would be lights over two different aquariums or if you use a Kessil fixture for your refugium, you could change the lights over the display tank independently of the refugium light. Powering the controller is a micro-USB that can be plugged into a wall outlet or computer USB port. When not plugged in, the controller retains all programs and settings, so all of that hard work isn’t lost when the controller is taken offline.

Beautiful New Liopropoma Species Discovered

golden bass Beautiful New Liopropoma Species DiscoveredA gorgeous  new Liopropoma  species has recently been discovered in the Caribbean. The new species, Liopropoma santi now dubbed the  “Spot-tail Golden Bass” has a striking mostly yellow-gold body and shares many physical similarities to other recently discovered deep water “Golden Bass”.  In fact, scientists originally thought the fish was the Liopropoma olneyi due to their nearly identical morphology and not a new species at all.   Liopropoma santi  was only identified as a unique species after extensive DNA analysis. “This under explored zone between 60 and 300 m in the tropical southern Caribbean is revealing extraordinary biodiversity, including a wealth of new species of beautifully colored fishes. It’s a zone that science has largely missed because it’s too deep to access using scuba gear, and deep-diving submersibles rarely stop at such shallow depths.” said C. Baldwin, one of the researchers begin the discovery. Over the past few years deep water Caribbean Bass like Liopropoma aberrans , have become the must have rare fish for high hard core aquarium enthusiasts. With some specimens commanding prices of  $9,000 or more. As such, it is probably just a matter of time until a Spot-tail Golden Bass ends up in a high-end rare fish buff’s reef tank. MORE
