This is the Turbo Floter Multi and a link to the Aqua Medic website. You can do click on the link for dealers. I didn't see the Biostar Floater badboy (welcome!), I either missed it or maybe you could find a link for us.
Turboflotor Multi SL motor driven outside protein skimmer for aquaria from 600 Liter (150 Gallons) 
The Turboflotor Multi SL is our most versatile protein skimmer. It can be fixed to the side of the aquarium (´hang-on´ mode), or placed inside or outside the sump of the filter. Its compact size makes it small enough to be stored under the cabinet.
In the ´hang-on´mode, only the pump is placed inside the aquarium. The pump Ocean Runner PH 2500, 37 W, features a venturi with the patented Aqua Medic needle wheel. The skimmer itself has the conical collection cup inner tube (also patented), and a lid, and two outflow boxes for directing the outflow back into the aquarium.
As an option, a large 1.2 litre (0.3 gallon) Filter Box can be placed at the outlets, for use as a first stage biological filter.
