The Hydros DC CO2 Solenoid Valve gives reef and planted tank keepers precise, app-controlled management of CO2 flow without the clutter of extra power adapters. Plugging directly into a Drive Port on the Hydros Control 2 or Control 4, it draws power from the controller itself and appears immediately in the Hydros app as a controllable device. The result is a straightforward installation that fits cleanly into an existing Hydros ecosystem.
For reef aquariums running a calcium reactor, the solenoid pairs naturally with a pH probe connected to the same controller. Users can configure automated rules that open the valve when pH rises above a set threshold and close it when pH drops too low, keeping media dissolution rates consistent without manual intervention. The same logic applies to freshwater planted tanks where stable CO2 injection directly influences plant growth and water chemistry.
The valve is manufactured by AutoAqua in Taiwan, the company behind the widely used Smart ATO Micro. CoralVue tested the unit specifically for compatibility with the Hydros platform and engineered the connection around an aviation-style plug for a more secure and reliable interface than a standard barrel connector. No secondary power source is required.
This solenoid is purpose-built for the Hydros Control 2 and Control 4 — it will not function independently or with third-party controllers. Buyers running other automation platforms should confirm Drive Port compatibility before purchasing. A one-year limited warranty covers defects in materials and workmanship from the date of purchase.
