Small Sphere EcoSphere (4″ diameter) with turntable base. 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. Visible light, either artificial or natural, keeps the algae growing. There are no feeding or water changes required. Each EcoSphere comes with a replacement, recharge, or upgrade policy.
