The world of probiotics and carbon dosing can be a confusing one to many aquarium keepers. This fairly new trend in the saltwater aquarium hobby, in a nutshell, revolves around dosing and feeding nitrifying bacteria. To clear up any confusion about this filtration method, the crew at Marine Depot has created a dedicated forum to discussing nothing but biopellet media, Zeovit, Prodibio, and all other sorts of dosing systems. The forum, which is called the Probiotics and Labile Organic Carbon Dosing forum, is moderated by aquarium hobbyist and seasoned probiotics expert Murray Camp. And to celebrate the release of this new forum, Marine Depot is giving away some nice biopellet related gear. To enter the contest, all you have to do is post something in the official giveaway thread on their forums. The contest is open only to legal US residents 18 and over, with the winner receiving a Two Little Fishes NPX Bioplastics Reactor 150 with 200ml of NPX media.
