This is similar to the system we are creating. it will become necessary instead of a luxury in the coming years. When a group of people lay claim to all life on the planet and subsequently decide to spray that life from the belly of an airplane and kill it they are claiming ownership. That means people, plants and animals.
The soil is dying. The bugs, the plants, they animals and oceans. This type of system could help people who live in an apartment as well as those who have their own house. It is something that can be set up for a single person or a family. Growing in small spaces.
The fish tank we built is 600 gallons. and 12′ x 4′ x 4′ a little bit bigger then this video. This video though does show how easy it is to create.
The video below is large scale Aquaponics. It is more along the line of the one we are building. We are not doing for commercial use. Just for us and our animals. plus, fresh fish!
