Aquario Neo CO2 Extended Special Diffuser

If you are running a deeper rimless tank or a setup with serious vertical height, getting your gas all the way down to the substrate can mean running a messy trail of flexible tubing straight down your display glass. The Aquario Neo CO₂ Extended Special Diffuser solves this beautifully by giving you a super-extended tube. This allows you to position the diffuser head exactly where you want it without running flexible lines inside the tank. Even better, the Special series completely strips away the built-in bubble counter for an ultra-streamlined, low-profile look.

Key Features & Benefits

• An extra-long 15.65-inch tube easily reaches the bottom of deep aquariums, ensuring your gas dissolves thoroughly before hitting the surface.
• The minimalist Special design completely removes the built-in bubble counter for a sleek, low-profile look that keeps the focus on your aquascape.
• The heavy-duty acrylic construction is shatterproof, giving you a worry-free alternative to notoriously fragile glass diffusers.
• The extended acrylic body can be gently heated and custom-bent to fit your exact tank rim profile perfectly.
• When it comes to plant growth, bubble size is everything. Under 150x magnification, the Aquario Neo ceramic disc reveals thousands of ultra-porous nanoholes that outclass standard name-brand glass diffusers.

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.
