EcoSphere Closed Aquatic Ecosystem, Small Sphere, with Turntable Base

Small Sphere EcoSphere (4″ diameter) with turntable base. This fascinating enclosed world accommodates 3 to 4 marine shrimp, algae and micro-organisms. Created from hand blown glass, each and every EcoSphere is a fully enclosed, self-sustaining little world. The EcoSphere only needs indirect light and comfortable room temperature (between 60F and 80F.) The EcoSphere works at the basis that a closed system recycles its nutrients and does not produce excess waste. The shrimp consume the algae and micro-organisms they usually, in turn, break down the shrimp waste. External light, either artificial or natural, assists in keeping the algae growing. There is not any feeding or water changes required.
