Works great, they retail for about $50 or less. Rated for a 29gallon or smaller aquarium. I would buy another one if I had another nano tank. I currently use this one for my 29 gallon FOWLR tank and it produces a good amount of skimmate and I do not over feed my fish...
It is meant for a BioCube nano aquarium but can be used universally for any other type of aquarium. Hang it or attach it to your display tank or in you sump refugium filter like i did... ***The Clown Fish in the video is aclimmating/ quarantine there only temporarily before I put it in my display tank soon***
