Chihiros CO2 Regulator Mate - Pressure Regulator with Bubble Counter and Solenoid Valve

The Chihiros CO2 Regulator Mate is a high-precision pressure regulator with integrated bubble counter and solenoid valve. Compatible with refillable CO2 cylinders with standard W21.8 x 1/14 connection. Practical and precise, ideal for CO2 systems in planted aquariums.

💡 Expert tip: The integrated solenoid valve is crucial: connect it to your light timer to automatically stop CO2 delivery during the night, when plants do not photosynthesize and pH could drop dangerously. The integrated bubble counter allows you to precisely calibrate the flow — for most planted aquariums, start with 1-2 bubbles per second and adjust based on pH and KH values.
