Reef One has a new desktop acrylic tank to show off named biOrb Flow.  Available in both 15 and 30 liter sizes, the tank has integrated LED and a filtration system that is easy to clean and replace.  The media in the filter cartridge should be changed every 4-6 weeks according to the brochure.  What really caught our eye though was how nicely the system was integrated right down to the cable management.  You can order this new biOrb now, but follow the link for additional photos of the tank.
