Hygger Aquarium Auto Top Off System (ATO) HG987
verfill Protection
The ATO system alerts with a flashing LED light and beeping sound if there is any malfunctioning with the device itself, it uses a top sensor to sense the high water level, and auto shut off the water pump when the water level exceeds the desired maximum top-off level.
Dual Fail-Safe Design
hygger auto top-off kit is composed of a controller and a magnetic suction cup. The magnetic suction cup is installed on the inner side, and the controller is installed on the outer side. It is aligned with the water level line that needs to be detected, and then the power is inserted into the controller and powered on to perform the detection. Additionally equipped with one external sensor that monitors the reservoir’s water level to ensure the pump not running dry as a result of water drying out.DC-powered Water Pump
Comes with a mini DC-powered water pump and a soft hose that can effectively pump water from a bucket/jug with a head height of up to 2 meters. the water pump has a max lift of 4.9 ft, make sure the height from the water pump to the aquarium is not higher than 4.9ft. Vice versa, it can also drain dirty water out of the tank with a 74 GPH flow rate.
Keeps Hose in Place
For rimmed or rimless aquariums up to 3/4 inch, make sure the 5.9ft soft water hose is installed above the water level so it won’t siphon when the pump cuts off.
External Sensors
Installed an external sensor on the reservoir wall, or put it in the reservoir if the tank wall is too thick. With a 5.1 ft cable length, the external sensor should be higher than the water pump, ensuring that the pump does not burn out as a result of water drying out.
How Does it Work
This auto top-off system adopts double optical sensors and is mainly used to monitor water shortage and full water status, and control water pumps and solenoid valves.
