Using a bubble counter you have a visual display of the amount of CO2 you are diffusing in your aquarium. You can therefore accurately adjust the flow of CO2, ensuring you are making correct adjustments to suit the dosing for your aquarium.

The integrated check valve prevents water from siphoning from your bubble counter into sensitive and expensive equipment such as your regulator or solenoid.
