Acrylic CO₂ Diffuser


  • Ultra-Fine CO₂ Bubbles: Features a micro-pore ceramic disc that produces fine, evenly dispersed CO₂ bubbles for improved distribution and more effective absorption by aquatic plants.
  • Built-in Check Valve & Bubble Counter: The integrated check valve prevents backflow to protect your CO₂ system, while the water-filled chamber doubles as a bubble counter for easy flow monitoring.
  • Durable Shatter-Resistant Acrylic: Made from high-quality acrylic with glass-like clarity—stronger and more durable than glass, while remaining easy to observe during operation.
  • Secure Ceramic Disc Construction: The ceramic disc is permanently bonded to the chamber with a tight seal, ensuring stable performance under pressure and consistent fine-bubble diffusion.
  • Multiple Sizes & Easy Installation: Available in three sizes—S (up to 13 gal), M (13–32 gal), and L (32+ gal). Includes a syringe, suction cup, and tubing for quick and convenient setup.

Produces very tiny bubbles, very impressive even with lower pressure.

I couldn’t be happier with this diffuser! The build quality is excellent and the clear acrylic design blends seamlessly into my aquarium setup. The built-in check valve and bubble counter are incredibly handy, making CO₂ monitoring simple and efficient without extra parts or clutter. It produces a fine, consistent mist of CO₂ bubbles. Setup was straightforward. This is a solid, reliable, and does exactly what it promises. I highly recommend this diffuser for all hobby starters.

Excellent diffuser. It looks like glass but it’s way more durable. The bubble counter works well and it makes extremely fine bubbles in the water. The white ceramic works better than brown for me because I can easily see if it needs to be cleaned.
