I am working on a desktop aquaponic system. It is going to use goldfish as the fish and just grow a few plants. I am planning on doing a flood and drain system, and a continuous flow system. I have a video up of me testing the bell siphon and a brief description of how I built it.
Nicholas, that is to cool. I bet if you get this going and pretty it up some you could sell them.
There are lots of folks who like aquariums and like to grow plants !
