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 triple water level sensor for added security. It is perfect for maintaining water levels in small aquariums or all-in-one tanks with low water fluctuation.

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)
