The Red Sea ReefATO+ is a highly dependable automatic top-off system designed to maintain stable salinity and water volume in reef aquariums. This advanced device combines precise temperature monitoring and an external leak detector to ensure optimal aquarium conditions, automatically replenishing water lost to evaporation.

Key Features:

• Fail-proof Water Level Sensor: Solid-state with a built-in safety shutoff.

The ReefATO+ employs titanium probes to accurately detect water levels, ensuring your aquarium remains within a precise 3mm band. Its microprocessor-controlled pump is equipped with safety features such as auto-shutdown to prevent damage from running dry or excessive operation. The higher-level backup probes only activate when necessary, avoiding false alarms from routine water fluctuations.

For existing Red Sea Reefer aquarium owners, a dedicated ReefATO+ upgrade kit offers a seamless transition from the standard gravity-fed float valve system, making it a cost-effective enhancement.

Ensure your reef aquarium's stability with the Red Sea ReefATO+, the ultimate solution for precise water and salinity management.
