HYDROS Auto-Top-Off Kit – Coralvue

Product details

HYDROS Auto-Top-Off Kit – Coralvue is an add-on kit that lets you turn your HYDROS Control device into a complete auto top-off (ATO) system. In day-to-day reefkeeping and freshwater setups, stable evaporation compensation helps keep salinity (in saltwater) or overall water volume steadier—reducing swing-driven stress from fluctuating water levels. This kit is intended for tanks where water fluctuation from evaporation is relatively low, such as small aquariums or many all-in-one (AIO) style tanks.

Features:

• Transforms a compatible HYDROS Control device into an auto top-off system for automated water-level maintenance
• Includes the components needed to run an ATO setup without purchasing a separate, standalone ATO unit
• Helps maintain consistent aquarium water levels to support long-term stability
• Well-suited for small aquariums and AIO tanks where evaporation-driven water level changes are typically modest
• Practical choice if you already use (or plan to use) a HYDROS Control device and want tighter integration

Specifications:

• Product type: Auto top-off (ATO) add-on kit
• Compatibility: Designed to work with a HYDROS Control device
