Ecosphere Closed Aquatic Ecosystem Small Pod

This fascinating enclosed world contains 3 to 4 marine shrimp algae and a sea-fan. 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 alga which breaks 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.
