The first thing you need to have in an aquaponics system is a way to hold water. In order to achieve system stability and grow an interesting quantity of food and fish, you’ll want to shoot for a water volume of 250 gallons. That’s a lot of water. There are a lot of options. Concrete ponds, International Bulk Container (IBC) totes, 55-gallon drums, wood structures lined with plastic. For the 365 Aquaponics system, I chose stock tanks. Here are my reasons for using stock tanks. They are an existing and proven product. Stock tanks were designed to hold water for cattle, sheep, and other large livestock. They were designed to withstand day to day abuse from such livestock and the elements in which the livestock lives. Because plastic stock tanks are rugged, large capacity, and constructed from food grade plastic, they are often used by restaurants for food storage and preparation. Perhaps most important, they should be locally available. When you’re buying something this big and having it delivered to your home, you’ll pay a hundred dollars or more just for shipping. If you can get it in stock from a local agriculture store, the shipping to the store has already been covered by the store as part of the cost of doing business. They require little modification, if any. Grow beds in the 365 Aquaponics System have a single easy to drill hole (1” if using ‘English’ units, 25 mm if using metric). Beyond stacking some cinder blocks and planks, I don’t need to build support structures. So here’s a video clip showing me preparing the stock tanks for the 365 Aquaponics System.
