ATO systems are very important on saltwater aquariums and can give you more success, and time to enjoy your tank. Aquamedic's Auto Top Off System Pro is a well thought out, plug and play design that incorporates every aspect of a safe and reliable ATO system.

  • Water resistant controller
  • Optical water level sensors
  • Backup level sensor
  • Empty reservoir sensor
  • Dry-run protection
  • Audible and visible alarms
  • Low voltage


ATO systems are easily one of the most important pieces of equipment on a saltwater aquarium. By keeping your tanks water level steady you will also benefit from a constant salinity, not to mention the daily task of adding water to the aquarium or sump will be removed.

Aqua Medic's Auto Top Off System Pro is a well thought out, fail-safe design that uses multiple sensors to monitor the fluid level of your aquarium, and also warns you when your top off reservoir is getting low. The ATO Pro utilizes an optical sensor as the main level sensor to continuously monitor the water level and has a backup sensor that goes above the optical sensor. The entire ATO system will shut the system down if water ever gets too high and triggers the backup sensor.
