The Radion is fully compatible with the EcoTech Battery Backup.
In the event of a power outage, lack of light energy over the aquarium results in corals switching from photosynthesis (producing oxygen) to respiration (consuming oxygen). When used with a Battery Backup accessory, the Radion emits low levels of light intended to prevent corals from respiring, and therefore; your Radion will help to maintain an oxygen-rich environment for your fish during this critical time period.
