## Summary description

sera flore CO2 bubble counter is a single-piece aquarium accessory designed to visually monitor CO2 injection by counting gas bubbles. Supplied as one unit per pack, it connects in-line with CO2 tubing to help regulate dosing for planted aquariums and hydroponic systems. Useful for hobbyists tracking CO2 flow rate and adjusting diffusors or regulators.

## Long description

The sera flore CO2 bubble counter is a single-piece aquarium accessory that provides a clear visual method for monitoring CO2 injection by counting gas bubbles. Designed for in-line connection with standard CO2 tubing, this compact bubble counter offers precise bubble separation thanks to an internal fine nozzle, enabling hobbyists to observe and control CO2 dosing for planted aquariums and small hydroponic setups. Supplied as one unit per pack, it is unobtrusive and suitable for placement near the regulator or diffuser line.
Advantages
The single-piece design simplifies installation and reduces potential leak points compared with multi-part counters. The internal fine nozzle produces distinct, well-separated bubbles that make it easier to count and measure CO2 flow rates. Its compact dimensions allow discreet placement inside or outside the aquarium cabinet, while the transparent body gives continuous visual feedback without the need for additional tools.
Suitable for
 Monitoring CO2 dosing in planted aquariums
 Adjusting regulators and diffusors by bubble rate observation
 Small-scale hydroponic systems requiring visual CO2 flow checks
 Routine maintenance checks by aquarium hobbyists
Key specifications
 Material: transparent plastic body for visual bubble observation
 Design: single-piece construction with integrated fine nozzle
 Connection: in-line installation with standard CO2 tubing (push-fit style)
 Pack contents: one bubble counter per pack
 Application: suitable for low to moderate CO2 flow rates typical of planted aquaria
How to use
Install the bubble counter in-line between the CO2 regulator or cylinder outlet and the diffuser by cutting the CO2 tubing and inserting the tubing ends onto the barbed connections. Fill the bubble counter partially with water to allow bubble formation; avoid overfilling to ensure clear bubble separation. Start the CO2 supply and observe the bubble frequency through the transparent body. Count bubbles per minute to determine the current dosing rate and adjust the regulator or needle valve until the desired bubble rate is reached.
Usage recommendations
Place the bubble counter where it is easy to see during routine checks and protected from direct sunlight to limit algae growth. Use clean, dechlorinated water in the chamber and inspect tubing connections periodically for secure seating. For consistent measurements, allow the system to stabilize after each adjustment and record bubble counts under similar conditions (same water temperature and pressure conditions).
