Description
The Chihiros CO2 Regulator PRO - Limited Edition is a precise CO2 regulator with dual pressure gauges for stable and fine adjustment of CO2 supply in the aquarium. It is suitable for standard CO2 cylinders with CGA320 and W21,8 threads, allowing precise control of the bubble count for optimal CO2 supply to aquarium plants.
This limited edition differs from the regular Chihiros CO2 Regulator PRO with color-coded pressure gauges and design-matched screws, enhancing the overall aesthetic appearance.
The integrated 12V DC solenoid valve ensures safe and energy-efficient operation, while the built-in safety valve automatically relieves pressure if it exceeds 100 PSI. The included bubble counter with a check valve prevents water from flowing back into the system.
The included Chihiros Controller for CO2 regulators with solenoid valves can be controlled and programmed via the MyChihiros app using a Bluetooth connection. This allows setting time periods when the valve allows CO2 flow or shuts off CO2. The Chihiros Controller is simply connected via a plug-in connection and is immediately ready for use.
