Seachem Glass Bubble Counting Diffuser – 17 mm

The Seachem Glass Bubble Counting Diffuser combines two essential CO₂ components into one elegant glass device. Acting as both a bubble counter and diffuser, it allows aquarists to monitor CO₂ injection rates while simultaneously producing a fine mist of CO₂ micro-bubbles for efficient dissolution.

Its compact 17 mm design is ideal for nano and smaller planted aquariums, helping maintain a clean and minimalist appearance without multiple pieces of equipment cluttering the tank.

Key Features

• Integrated bubble counter and diffuser

Installation Tips

• Place the diffuser near the bottom of the aquarium.
• Position beneath filter flow for better CO₂ circulation.
• Fill the bubble counter chamber with water before use.
• Allow the ceramic disc to soak before initial installation.
• Monitor bubble rate to maintain consistent CO₂ levels.

Tip: Positioning the diffuser near filter outflow helps distribute CO₂-rich water more evenly throughout the aquarium.
