Corals Stir up Their Own Cocktails

A new paper published by MIT has provided a deeper understanding into how coral utilize their external cilia in respiratory and metabolic processes. “These microenvironmental [findings] are not only important, but also unexpected,” says Roman Stocker, an associate professor at MIT and senior author of the paper.  “The general thinking has been that corals are completely dependent upon ambient flow, from tides and turbulence, to enable them to overcome diffusion limitation and facilitate the efficient supply of nutrients and the disposal of dissolved waste products,” adds Orr Shapiro, co-first author of the paper. “I was expecting that this would be a smooth microworld, there would be not much action except the external flow.” said Stocker. However, upon closer, microscopic inspection, he and his team found that it is in-fact “very violent.”140901211419 large Corals Stir up Their Own Cocktails “It appears that most if not all [coral] have the cilia that create these flows. The retention of cilia through 400 million years of evolution suggests that reef corals derive a substantial evolutionary advantage” Said Shapiro, and “It’s rare that you have a situation in which you see cilia on the outside of an animal,” adds Stocker. David Bourne, a researcher at the Australian Institute of Marine Science who was not connected with this research, says the work has “provided a major leap forward in understanding why corals are so efficient and thrive. … We finally have a greater understanding of why corals have been successful in establishing and providing the structural framework of coral reef ecosystems.” Read more here!More:

Return Pumps: tests and real measurements compared

DSF 8985 Return Pumps: tests and real measurements compared

The project of the return pumps is now old and started with the previous article “return pumps: calculating the flow” that I invite you to read, and where I proposed an excel file, downloadable, editable with most of the pumps on the market, which were often recommended as return pumps in the forums and among hobbyists. The file made possible from the data of the pumps and the prevalence of each tank, get a pump flow rate calculated for each individual pump.

Although the file would be updated by anyone, I was always curious to know how pumps would behave in reality as well as declared by individual manufacturers.

During the Zoomark held in Bologna, Italy last year, we decided to contact some companies in the aquarium industry to do a comparative test of the pumps.

Some have enthusiastically joined, in true alphabetical order, Eheim, Tunzeand Sicce, and they have provided the pumps subject of our comprensive test.… More:
