The CoralVue Hydros Auto Top-Off (ATO) Kit (HDRS-ATO-202H) comes with everything you need to use your Hydros device (Control 2 or Control 4) as an ATO system. NOTE: You must have a Hydros Controller (Control 2 or Control 4) for this product.
The Hydros Water Level Sensor contains no moving parts that can fail. It’s extremely tiny: it’s a little over a half-inch thick with a circumference the size of a US penny. The optical eye is magnetically coupled with the magnet side measuring only 1/4" thick. It can be mounted to most clear, tinted, or painted surfaces up to ½” thick. The sensor connects with any Hydros Sense Port using an aviation-style plug for safe operation. No additional power source is needed to run the sensor.
The Hydros DC Micro Pump is powerful despite its small size. The pump measures 1.6” L x 1.062” W x 1.45” H. The pump has a maximum head pressure of 8’. The flow rate of the pump is 74 gallons per hour. This 12V brushless pump draws a maximum of 4.5W and has an average life expectancy of 30,000 hours (over 3 years). When connected to a Drive Port on the Hydros Control 2 or Control 4, the controller will supply power to the pump so no additional cords or power bricks are required for operation. Using a Hydros aquarium controller for your auto top-off system is not only a reliable solution, but it also helps clear wire clutter in and around your aquarium.
