This is a good gauge as to how much visible algae should be in the system. Temperatures above 85 degrees put excess stress on the shrimp in the EcoSphere. Temperatures below 60 degrees slowdown the metabolism of the shrimp. DO NOT let the temperatures flux erratically from 60 degrees to 85 degrees. The temperature needs to be consistent.
Sudden changes can affect the life of the system.
DO provide artificial light or indirect sunlight for your EcoSphere for at least 6 to 12 hours per day. The intensity can be suitable for plants needing low levels of light. Lamps Indirect window sunlight DO NOT let your EcoSphere get too hot or too cold. We may think the temperature is fine but an Ecosphere can warm up and cool down as easily as a glass of water. So a rule of thumb, be aware of the temperature of the room.
