Me CO2 Regulator Basic, Pressure Regulator – Precise CO2 Control for Aquariums

Key Features:

• Compact CO2 pressure regulator with 2 gauges
• Displays cylinder pressure & working pressure
• Preset working pressure approx. 1 bar
• Standard W21.8 connection – suitable for common refillable cylinders
• Stable CO2 supply for healthy plant growth

Product Description:

The Me CO2 Regulator Basic is a compact and reliable pressure regulator for precise control of CO2 supply in aquariums. It ensures a stable and consistent CO2 supply, supporting healthy plant growth and stable water parameters.

The regulator is equipped with gauges that clearly display both cylinder pressure and working pressure. The preset working pressure of approx. 1 bar (adjustable from 0–3 bar) ensures consistent CO2 output, while the finely adjustable valve allows precise dosing.
Thanks to the standardized W21.8 connection thread, the Me CO2 Regulator Basic is compatible with most common refillable CO2 cylinders and is ready for immediate use. Its compact design is particularly suited for upright installation, for example in combination with suitable adapters such as the Me CO2 Adapter M10×1.25 ? W21.8 for use with disposable cylinders.

NOTE:
If the Me CO2 Regulator Basic is operated directly on a refillable CO2 cylinder, the CO2 Control Night (night shut-off with integrated bubble counter) should not be mounted directly onto the regulator. In this configuration, the night shut-off would be positioned sideways, preventing the integrated bubble counter from functioning correctly.

However, the CO2 Control Night can be used without issue if it is installed in an upright position via a CO2 hose. In this orientation, reliable bubble counting is ensured.

Compact, robust, and easy to use – the Me CO2 Regulator Basic is the ideal foundation for an efficient and reliable CO2 supply in your aquarium.
