Porcupine Puffer (Diodon holocanthus)

Posted on Wednesday, March 14th, 2012 at 2:59 pm

The Porcupine Puffer, Diodon holocanthus, sometimes called the Porcupinefish is named for the spiny appendages covering almost the entirety of it’s body. The Porcupine Puffers body is “camouflaged” with a variety of gray and tan spots.

As a primary defense system, the Porcupine Puffer is able to inflate it’s body to almost double it’s vertical height by swallowing water or air. The sharp spines are used as a secondary defense mechanism when this fish feels threatened. Some species are poisonous, with a tetrodotoxin being present in some of their internal organs. This neurotoxin, believed to be produced by several types of bacteria obtained in this puffer’s diet, is at least 1200 times more potent than cyanide.

An well-skimmed FISH-ONLY aquarium of 180 gallons or more is ideal. It is important to note that this fish may be aggressive at times, and may nip at other tank mates. This puffer will eat invertebrates often found in reef tanks, so again, a fish-only tank is the best choice.

The Porcupine Puffer should be offered a varied diet consisting of meaty foods (clams, squid, krill, clams, etc). Hard-shelled shrimp will help file back this puffer’s ever-growing teeth.

CAD Light upgrades the Conic Bio-reactor

Posted on Wednesday, March 14th, 2012 at 2:28 pm

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.

Infra Red Fish Nets by Penn Plax

Posted on Tuesday, March 13th, 2012 at 9:55 am

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?

Controllable Flow DC Pumps by Waveline

Posted on Tuesday, March 13th, 2012 at 9:24 am

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.
