Aquario Neo CO2 Extended Original Diffuser

If you are running a deeper display tank or a setup with a bit more vertical height, standard short diffusers just won't cut it. The Aquario Neo CO₂ Extended Original series fixes this by adding an extra-long tube body so you can position the diffuser head exactly where it belongs: low down near the substrate. It keeps the built-in bubble counter chamber right at the base for easy monitoring, and it is made from an ultra-clear, shatterproof acrylic that delivers the crisp look of glass without the stress of accidental cracks.

Key Features & Benefits

• An extra-long connector tube is specifically designed for deep tanks, letting you mount the diffuser head low for maximum gas dissolution time.
• An integrated bubble counter chamber design lets you track your daily dosing rate easily without adding external inline equipment clutter.
• The heavy-duty acrylic construction is shatterproof, providing vast safety improvements over fragile, easy-to-snap glass alternatives.

Additional Information

• Submerge the entire diffuser in clean water for 30 minutes before connecting it to your gas line. This primes the micro-pores of the ceramic membrane, ensuring it produces a fine mist instantly on startup rather than large, wasteful bubbles.
• Over time, natural organic film or algae can accumulate on the ceramic surface, causing the bubbles to grow larger. When this happens, simply soak the diffuser in standard household bleach for 10 minutes, then rinse it thoroughly with fresh water and a generous dose of aquarium water conditioner to completely neutralize any residual bleach before placing it back in your tank.
