M10 CO2 Bubble Counter

The M10 CO2 bubble counter threads directly into a CO2 regulator or needle valve using a standard M10 connection. It provides a clear visual reference for adjusting and maintaining a consistent CO2 injection rate in planted aquariums.

The clear chamber allows bubbles to be counted easily at a glance, making fine adjustments straightforward and repeatable. This direct mount design keeps the setup compact and eliminates the need for inline fittings.

We suggest filling the bubble counter with organic vegetable glycerin for smooth, long lasting, consistent bubble formation.

This model includes a built in check valve. For added protection, we recommend using an additional standalone check valve installed closer to the aquarium.
