Orphek Nilus – 24” 120 Watt LED Fixture

Posted on Friday, February 24th, 2012 at 11:06 am

Orphek has stepped up their game, quickly racing towards the top of the LED aquarium lighting market. ReefTools recently introduced the Orphek PR-156 to our community, now we would like to introduce its big brother, the Orphek Nilus. The Nilus looks very similar to the PR-156 since Orphek maintained the stylish designed. The biggest changes are in the controller, it is now equipped with dimming functions capable of independently dimming the white and blue LEDs. This coupled with the controller’s timers gives the aquarist absolute control over the look of their reef. The controller can be programmed for multiple intensities through out the day creating a nice sunrise to sunset look. Orphek states the dimmer spent a year in research and design perfecting the fixtures ability to maintain the spectrum output while being dimmed. To obtain the “perfect” spectrum for SPS corals Orphek added additional diodes with varying colors. We are looking forward to the opportunity to see these in action.

90 Mile Wide Underwater Storm

Posted on Wednesday, February 22nd, 2012 at 11:16 am

Nasa satellites have capture images of a giant underwater storm called an eddy off South Africa. The eddy stretches approximately 90 miles across and it was first spotted back in December. It was stated the storm poses no threat to sea life or shipping lanes, in fact it is believed the massive swirl will pull nutrient rich particles from the ocean’s floor to the surface. It could be Mother Nature’s way of spring cleaning.
