CoralVue HYDROS Triple Optical Auto Top-Off (ATO) Kit

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 X2 or Control X4) as an ATO system. This kit features a new Triple water level sensor for added security. 

The HYDROS Auto Top-Off Kit Includes:

  • HYDROS Triple Water Level Sensor (plugs into HYDROS Sense Port)
  • HYDROS DC Micro Pump (plugs into HYDROS Drive Port)
  • Hang-On Tubing Mount
  • 80" Tubing (8.5mm OD - 6.5mm ID)
  • Siphon Break


HYDROS Water Level Sensor: An Easy and Accurate Way to Monitor Your Water Level!

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.

HYDROS DC Micro Pump: Controlled and Powered by HYDROS to Top-Off Your Tank!

The HYDROS DC Micro Pump is powerful despite its small size. The pump measures 1.57” L x 1.46” W x 1.5” H. The pump has a maximum head pressure of 6’. The flow rate of the pump is 50 gallons per hour. This 12V brushless pump draws a maximum of 5W and has an average life expectancy of 30,000 hours (over 3 years). When connected to a Drive Port on the HYDROS Control X2 or Control X4, 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.
