me Aquaristic Me CO2 Control Night, Solenoid Valve with Integrated Bubble Counter

Optimise your CO₂ supply while saving valuable gas! The Me CO₂ Control Night Solenoid Valve by me Aquaristik is the smart solution for precise and efficient CO₂ regulation in your aquarium.

This combination unit features a reliable solenoid valve integrated with a bubble counter. The key advantage: when paired with a simple timer (sold separately), you can enable automatic night shut-off. Since plants don’t absorb CO₂ at night, the valve automatically stops gas flow during the dark phase — preventing waste and saving you money.

During the day, the gas is released in a controlled and precise manner. The integrated bubble counter allows you to keep an accurate overview of the CO₂ flow at all times.
