Why Is an Accurate ATO Sensor Important?

An automatic top off sensor is one of the most important components of any reef aquarium. As water evaporates, only pure water is lost, leaving salt behind and causing salinity to increase. A reliable ATO sensor detects these changes and signals the ReefATO+ system to replace the evaporated water, helping maintain stable conditions for corals, fish and other marine livestock.

  • Maintains stable salinity
