Cad light has listened to the request of their costumers by engineering a 3-way re-circulating valve for their bio-pellet reactor. The 3-way valve gives the user the ability to completely control the rate the water moves into the reactor and leaves the reactor as well as the speed the bio-pellets tumble. This will help new users from common mistakes like overdosing or under dosing.
The intent was to make the controlling of the reactor extremely easy, which it seems they have done. Simply monitor the parameters of your system and adjust the speed of reaction required based on the flow rate you set. I haven’t had the opportunity to work with the new Conic Bio-reactor, but I am told they are in stock and ready to ship. As always, Reef Tools welcomes reader’s input.
Marine Depot has teamed up with Hydra Aquatics to offer a nice reward to a lucky winner. All that is required to be entered into the drawing is signing up for their newsletter before April 1st. Pretty simple.
Could it be this easy? I can’t say for sure, yet. Penn Plax has taken what the recreational fisherman has known for a long time and applied it to the fish hobby. Infra Red colored fish nets. It’s been a long standing claim that fish can not see the red spectrum, making fishing line virtually invisible to the fish. Will an infra red colored fish net make the net invisible? Time will tell. I will be ordering one soon. Penn Plax has released the net in a variety of sizes and handle lengths. From what I’ve seen the handles are black, could this be the weak link?
H20 Systems Inc. unveiled the Waveline DC-5000 at the Global Pet Expo in Orlando, Florida. DC pumps have several advantages, like lower power consumption, they can run substantially cooler and since the pump is a DC pump it can run off of a battery source or a solar panel. Power goes out, no problem. The CD-5000 is reported to consume 40W at the maximum speed pushing 1,320 gph.
The DC-5000 has 6 adjustable flow rates and is packaged with a controller. The flow from traditional pumps was only controllable by restricting the flow by way of a valve. The new DC-5000 reduces the RPMs through the controller which also reduces the power consumption of the pump.
This new line of pumps opens up several new possibilities. Add the DC-5000 to a closed loop system using the controller to vary the flow from the pump could possibly replace the need for wavemakers and powerheads.
Advanced Aquarist revealed the DC-10000, which will push 2,640 gph. Here are the stats Advanced Aquarist released:
The product line is currently comprised of two models: The DC-5000 and the DC-10000. The DC-5000 is in production and the DC-10000 should be in production by the end of April 2012. A smaller DC-2500 model is also planned for the future.
Waveline pumps can be operated in-line or fully submersed.
As their model numbers imply, the pumps are direct-current (DC). DC pumps are considerably more efficient than common AC pumps and allow variable speed control by ramping up/down the motor’s RPM. Greater efficiency also results in less heat transference to your water.
The pumps will come complete with a standard controller (pictured below) that allows users to select between six preset speeds as well as engage a 10 minute feed mode with a push of a button.
H2O systems is working on an optional, advanced control module that will feature a photo cell (for day/night sensing), dynamic variable speed control, pulse mode ability, and interoperability with popular aquarium controllers like the APEX.
The DC-5000 outputs 1320gph (5000lph). The DC-10000 outputs 2640gph (10,000lph).
The DC-5000 consumes 40 watts. The DC-10000 consumes 85 watts.
The DC-5000’s MRSP is $239.99 USD. The DC-10000’s MSRP is $349.99 USD.
Waveline is now available in Canada and should appear in the USA very shortly.
The Florida Wildlife Commission (FWC) has produced several underwater recordings of native Florida fish species. Scientist studies the biological functions of animal sounds in research called bioacoustics. This method of studying fish is a noninvasive technique giving the researcher insight into fish behavior with no harm to the fish or disrupting their daily activities. FWC has made several recordings available through flickr.
Gary Stokes posted a video of 1,000s of shark fins laid out on a sidewalk in Hong Kong. Shark fin soup is a delicacy in many Asian countries. The method of chopping off the shark fin then dumping it over board and left to drawn is gut wrenching. This video helps put this practice into perspective. I’ve been reading article after article on the banning of harvesting shark fins for soup, but never really knew how large of a problem it is. This video clearly shows that something has to shut this industry down and quickly.
I’ve read that shark fins sell for as much as £380 a pound, which equates to $600 US dollars per pond.
The caption is difficult for me to follow. The video seems to be a sea krait trying to eat an eel. The sea krait is an amphibious snake which is a member of the subfamily Laticaudinae. These snakes are viviparous, meaning they return to land to lay their eggs, unlike true sea snakes. This species is venomous, scientist say their venom is ten times more deadly than a rattlesnake. Note the paddle-shaped tail which makes it a great swimmer.
GHL now offers a flow sensor designed for the ProfiLux aquarium controller. With this additional sensor ProfiLux can display the measured flow of your aquarium pump. If the flow of your pump falls below a given rate the controller will warn aquarist with an acoustic signal, send a SMS message to your phone or an email. The ProfiLux can even switch the failing pump off in extreme cases.
The ground was broken last Friday for the new Patricia and Phillip Frost Museum of Science. Construction of the new museum is expected to cost $275 million and be completed in 2015. The 250,000 square foot, eco friendly green building was designed by Grimshaw Architects base out of London & New York. Along with a staggering 600,000 gallon aquarium the museum will house a dome 3-D planetarium. Make sure to watch the fly through rendering. More information on the museum can be found on the Huffington Post.
