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. This EcoSphere comes with a Silver 4 LED base.

The LED base is a non-rotating lighted display base for the EcoSphere that is powered by a wall outlet, USB connexion, or 3 AAA batteries (not included). The LED can be changed to four different colours on a slow or fast pulse; or set to a particular colour. The algae in the EcoSphere may overgrow if the LED base is left on for too long.
