Keep salinity and your aquariums water level consistent with Reef Breeders low profile Prism-ATO. Water level changes are registered in fractions of a second using infrared level sensors and with all internal components built into the sensor, there are no additional controllers to mount. Reef Breeders Prism is designed to work with aquariums of all sizes, from pico desktops and All-in-One aquariums with limited space to large reef tanks with full sumps. Its small platform allows it to be installed unobtrusively almost anywhere! 

Three built-in infrared sensors

  • Low Level: If water drops below this point, the pump will be activated until the water hits the next sensor.
  • Fill Level: 2.5cm above the low-level sensor, this sensor turns the fill pump off when it detects water.
  • High Level: 2.5cm above the fill level, and 5cm above the low-level sensor, this sensor deactivates the pump when it senses water.
