The AQUA-NOA CO₂ bubble counter P with integrated one-way valve serves as a simple visual control for the CO₂ supply. The bubble counter is filled with water and connected to the CO₂ system. The number of bubbles also gives you a certain measure of the amount of carbon dioxide added to your plant aquarium. The one-way valve prevents returning water from damaging the pressure reducer or other parts of the CO₂ system.
Also well suited for Bio-CO₂ systems. The decreasing amount of bubbles makes it easy to tell when the fermentation solution has to be prepared again.
