Large Sphere Ecosphere. This fascinating enclosed world contains 12 to 13 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. Each Ecosphere comes with a replacement, recharge or upgrade policy.
