Aquarium Glass CO2 Diffuser Atomizer with U Tube Check Valve Suction Cup Premium Version

Right out of the box this thing started to produce small bubbles. You really should soften your airline in hot water before pushing it on though because it is glass. I'm only running one bubble every 2 seconds because it's just a little 5 gallon planted shrimp tank. I don't think you can replace the ceramic disc. It seems to be permanently attached. Also, there was no suction cup included to properly mount it. That's why 4 stars.

Looks good and works exactly as described. Easy to install — the suction cup holds it securely to the tank glass. The U-tube check valve prevents backflow, which gives peace of mind. Fine diffusion — the CO2 bubbles are tiny and disperse evenly, helping plants absorb it efficiently. Durable build — it feels solid and well-made, not cheap plastic. Cleaning is straightforward and doesn’t take much time. Overall, a reliable and effective CO2 diffuser for planted tanks.

Great diffuser works immediately and a good value.

Le doy 4 de las 5 estrellas por que las burbujas salen del centro nada mas. Hay un video que es muy gráfico en las reseñas. En lo particular me ha funcionado pero no como esperaba.

CO2 diffuser arrived on time , undamaged, I immediately rinsed it off and installed. it works WAY better than the air stone I've been using for CO2. I didn't need to heat my CO2 tubing because it was already stretched out adequately but I can tell that if I tried to force it in the diffuser stem ,I might break the stem. 10 out of 10. Would highly recommend.
