ATO-380P Aquarium Auto Top-Off System

Make routine aquarium replenishment more convenient with the ATO-380P top-off system. Optical sensing triggers supported refilling when the water level changes.

✅ Reduce repeated manual topping up - Automatic replenishment helps restore the set level during suitable normal operation.

✅ Use optical level sensing - The sensor provides the input for the configured refill response.

✅ Limit extended refill cycles - Runtime shutoff adds a supported limit to the automatic refill operation.

A More Consistent Aquarium Water Level

Match the system to the tank and replenishment reservoir before installation. Sensor position and the selected pump or solenoid arrangement determine how the setup responds to a level change.

Standard and solenoid packages have different components, with regional plug options for power. Follow the installation and maintenance instructions and check the system regularly rather than relying on unattended operation alone.
