The Chihiros CO2 Regulator Mate is designed for aquascapers who want a stable and precise CO2 supply without hassle. With dual pressure gauges, integrated solenoid valve and bubble counter, you get everything you need in one compact unit.

The regulator fits standard refillable CO2 cylinders with EU W21.8 thread and provides a smooth and easily adjustable working pressure. The fine needle valve makes it simple to set an exact and stable bubble rate, so your plants receive the CO2 they need without stressing fish and shrimp.

The built-in solenoid lets you switch CO2 on and off via a timer or smart plug, so CO2 is only added during the lighting period. This improves both plant growth and safety in the aquarium.
