CO2 Aquarium Bubble Counter XL - with Integrated Check Valve
A must have for any tank with CO2 injection, a bubble counter allows the user to estimate the CO2 injection rate by counting how many bubbles pass through the counter per minute.
A check valve prevents water from your aquarium from siphoning back into fragile and expensive CO2 equipment such as regulators and solenoids. Easy to read and easy to maintain.
How to use:
- Loose the cap ( upper part ) and fill the reservoir with clear water then fasten the cap firmly.
- Secure the CO2 pipe according to the inlet and outlet indication marks with the screw node.
