Great article on aquaponics from Graceful homesteading. They have a pretty nice pictorial on their set up. They tell us ” The best reason for using this kind of system is for sustainable and conservative use of water and for growth of vegetables and fish. It is traditionally used in areas that have little rainfall or where water is scarce.”
