An aquaponic aquarium combines a fish tank with a grow bed sitting on top: the fish water feeds the plants, which filter it in return. It is the simplest way to discover aquaponics indoors, in a kitchen, an office or a classroom, with herbs, lettuces or ornamental plants.
Place it near a bright window or add LED lighting, and monitor the water with a simple test. The article Aquaponics in the workplace and at school presents its educational uses.
