Siphon Filtration is a new company which produces a new wet-dry filter based on the old Carlson Surge device principle. Did we just say wet-dry filter? We meant to say tide influenced, biologically stimulating natural ebb and flow super filtration. Although Wet-dry filters may carry with them some negative connotation, this form of biological nitrification filtration is still the best at removing and processing the main byproducts of animal metabolism. The Siphon Filter is somewhat reminiscent of the Ebb & Flow filter from the old Aquatic Wildlife Company and that Bio-Rocker thingy which Kent Marine marketed for awhile. Although the Siphon Filter may also have some design throwbacks with some neon-colored acrylic panels used in teh construction, we are intrigued at how this kind of filtration may be able to increase dissolved oxygen better than a traditional wet-dry filter by constantly drawing and purging oxygen rich air through the biological chamber and it appears that certain models may have built in refugia and top off chambers. No word yet on pricing and availability but until we sort out those details, for now you’ll have to contend yourself with the website and video.
