Frequently Asked Questions
Q: What is a CO2 bubble counter and why do I need one in my aquarium?
A: A CO2 bubble counter is a small device installed in your CO2 injection line that allows you to visually count and monitor the rate at which carbon dioxide is being delivered to your aquarium. By observing the bubbles passing through the water-filled chamber, you can easily adjust your CO2 regulator to achieve the optimal flow rate for healthy aquatic plant growth.
Q: What does the built-in check valve do?
A: The integrated non-return (check) valve prevents water from flowing backward through your CO2 tubing when the system is turned off or when pressure drops. This protects your CO2 regulator and cylinder from water ingress and potential damage, extending the life of your entire CO2 system.
Q: What is the difference between the single head and double head versions?
A: The single head bubble counter has one CO2 outlet, making it ideal for supplying CO2 to a single aquarium or diffuser. The double head version features two outlets, allowing you to split your CO2 supply between two tanks or two diffusers simultaneously — perfect for multi-tank setups.
Q: What liquid should I put in the bubble counter chamber?
A: Plain water is recommended. Fill the chamber approximately 4/5 (80%) full. This water level allows you to clearly see and count each CO2 bubble as it passes through, giving you an accurate reading of your injection rate.
Q: Is this bubble counter compatible with standard aquarium CO2 tubing?
A: Yes. This CO2 bubble counter is designed to work with standard aquarium-grade CO2 tubing and is compatible with most pressurized CO2 systems, including regulators, diffusers, and reactors commonly used in planted tanks.
