Why purchase a separate and expensive auto top-off system when HYDROS can do the job for you? The HYDROS Auto Top-Off Kit comes with everything you need to use your HYDROS device (like the Control 2 or Control 4) as an ATO system.
The HYDROS Auto Top-Off Kit Includes:
HYDROS Water Level Sensor (plugs into HYDROS Sense Port)
HYDROS DC Micro Pump (plugs into HYDROS Drive Port)
Hang-On Tubing Mount
Tubing (8.5mm OD - 6.5mm ID)
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 ¼” thick. It can be mounted to most clear, tinted, or painted surfaces up to ½” thick. The sensor operates in the daytime or complete darkness so it’s safe for use hidden inside your aquarium stand or in the back chambers of an all-in-one aquarium. The sensor is easy to place, easy to move, and easy to clean. 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.
