No maintenance aquarium, a complete miniature world
World’s first totally enclosed ecosystem utilizing NASA technology
Unique gift item, a perfect blend of science and art.
Small Sphere EcoSphere (4″ diameter). This fascinating enclosed world contains 3 to 4 marine shrimp, algae, and micro-organisms. Made from hand-blown glass, each EcoSphere is a completely enclosed, self-sustaining little world. The EcoSphere only needs indirect light and comfortable room temperature (between 60F and 80F. ) The EcoSphere works on the basis that a closed system recycles its nutrients and does not produce excess waste. The shrimp consume the algae and micro-organisms and they, in turn, break down the shrimp waste. External light, either artificial or natural, keeps the algae growing. There are no feeding or water changes required.
