EcoSphere Extra Large Sphere

Description

Extra Large Sphere EcoSphere (9" diameter). This fascinating enclosed world contains 30 to 35 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 is no feeding or water changes required.
