The Chihiros CO2 Regulator Pro (Limited Edition) is a premium aquarium CO2 delivery system. It is designed for precise nutrient dosing in planted tanks. This special version elevates the standard model by introducing color-coded scaled dials. Additionally, it features design-matched adjustment screws for a sleeker aesthetic.

Key Technical Features:

• Dual Pressure Gauges: Allows you to check the internal pressure of the CO2 cylinder alongside the active working output pressure.
• Integrated 12V DC Solenoid: Operates safely at a lower power consumption while remaining highly stable.
• Built-in Safety Valve: Automatically releases gas pressure safely if internal pressure spikes past 100 PSI.
• Bubble Counter: Includes an integrated check valve to protect your equipment by preventing aquarium water from siphoning backward.
• Thread Compatibility: Features versatile native support for standard CGA320, W21.8, and G5/8 cylinder threads depending on your region.

Modular Expandability & Smart Integration:

• Multi-Tank Expansion: You can scale your system across multiple aquariums without buying a new regulator by adding up to four Chihiros Limited Edition Extensions, each featuring its own dedicated needle valve and bubble counter.
• MyChihiros App Control: Connecting the optional Chihiros separate solenoid controller allows you to automate and schedule your CO2 cycles via Bluetooth on the official mobile app.
