## Long description

The Hydor Aqua Natura glass bubble counter is a compact inline device for aquarium CO2 systems, designed to visualize and count CO2 bubbles and support precise dosing control. Made of clear glass with a slim cylindrical shape measuring 14 x 3 x 3 cm and weighing 15 g, it installs directly on CO2 tubing and provides a visible reference for bubble rate adjustment without affecting tubing routing or requiring large installation space.
Advantages
The bubble counter offers clear, immediate visual feedback on CO2 injection, allowing easy adjustment of bubble frequency. Its glass construction resists discoloration and provides an unobstructed view of bubbles. The compact dimensions and light weight make it suitable for tight setups and simple inline mounting, while the straightforward design requires no power or complex maintenance.
Suitable for
Planted aquaria where controlled CO2 dosing is required
Small to medium aquariums with limited installation space
Hobbyists monitoring and adjusting CO2 bubble rate manually
Key specifications
Material: transparent glass
Dimensions: 14 x 3 x 3 cm
Weight: 15 g
Inline installation for CO2 tubing
Visible bubble chamber for manual counting
How to use
Install the bubble counter inline on the CO2 tubing between the regulator and the diffuser or reactor. Ensure tubing fits snugly on both ends to prevent leaks. Fill the chamber partially with water if required by your system to improve bubble visibility and then slowly open the CO2 regulator. Observe the bubble frequency through the glass chamber and adjust the regulator or needle valve until the desired bubble rate is reached for your aquarium setup.
Usage recommendations
Place the bubble counter at a visible location and avoid direct contact with hard surfaces to prevent breakage. Periodically inspect for cracks and clean gently with soft water and a non-abrasive cloth. When not in use, store in a padded container to protect the glass.
