 There are many designs for an aquaponics system. This method, however, has been successful for our Aquaponics 101 workshop for teachers in the Auburn University School of Fisheries, Aquaculture and Aquatic Sciences. Using a single intermediate bulk container, consisting of a large 275 to 330 gallon capacity polyethylene vessel supported by an outer metal frame, is a relatively simple and inexpensive method. The other materials are generally available at most home supply or hardware stores. Once set up, these systems are simple to operate and maintain. This video presumes that you are familiar with aquaponics, particularly the ebb and flow style, also known as flood and drain, that allows plant roots to be in the water part of the time and in the air part of the time. We will demonstrate the construction of the four sections of the system. The fish tank, the grow bed, the bell siphon and the plumbing required to move the water. Safety always comes first, for you, the fish and the food that you produce. It's important when building an aquaponics system that you start with a clean container. Containers made from chemical resistant, high density polyethylene, also known as HDPE, are the best choice. Be sure that you know what was in the container. The most desirable ones were previously used for food products. For IBCs that contain food products, clean the inside of the pieces using dish soap as acceptable and make sure to rinse thoroughly with a water hose or pressure washer to ensure that there is no residue from the previous cargo. For an IBC that contained chemicals, refer to the appropriate material safety data sheet, also known as MSDS, to determine how to clean it properly.
