Blue Marine Automatic Top‑Off (ATO) system is designed to automatically maintain a stable water level in the aquarium or sump. When water evaporates, the infrared sensor detects the drop in water level and activates the pump, which refills the system with fresh water from an external reservoir.

The system is delivered as a complete kit and includes an infrared sensor, refill pump and hoses. The triple‑point detection sensor combined with LED indicators and a visual alarm increases operational safety and helps prevent overfilling or pump dry‑run. In case of malfunction, the system stops automatically and alerts the user with a flashing red LED.

Blue Marine ATO is easy to install and suitable for both freshwater and marine aquariums. Maintaining a constant water level helps stabilize salinity, protects equipment and reduces the need for manual top‑offs.
