  • Fine bubbles and built in bubble counter!
Size: L-24mm
The media could not be loaded. I’m sure what the other reviewers were about but this work greats!! It produce small enough bubbles that dissolve very well even for shallow tanks. The suctions on the diffuser has not failed even when I accidentally push it around. That and my plants are definitely growing well while it also helps me fight the BBA algae, amazing product and easily a good investment. Also the built in bubble counter was a nice touch ;) ... show more

  • Works very well
Size: M-17mm
I’ve had this diffuser running for a couple days now and I’ve had zero issues. It produces very small bubbles, and mists the tank well. I have it running on about 0.5 bubbles per second right now.

  • Great quality with super small bubbles
Size: L-24mm
The media could not be loaded. Extremely satisfied with the fzone diffuser . Purchased one for my 50 gallon aquarium and love how small the bubbles are coming out of the diffuser. Love how well it works and would highly recommend!

  • Great Value
Size: S-13mm
In just a matter of days this nano diffuser did what it was built to do. Very tiny micro bubbles with even distribution throughout the aquarium. With only 5 days of running it I’ve seen a massive improvement on plant growth. Easy to connect, perfect size, affordable price point and accurate distribution per the vendor. Ordered a few more for all my other tanks! Thanks again Fzone, as usual. You always aim to please! ... show more

  • Good product. Recommended. Customer Support is very efficient!
Size: M-17mm
Air doesn't come out. Soaked for 2 days and nothing. Tried blowing and nothing. I need help from the provider. Works well. This needs 15 to 20 PSI to start flowing. If not, air will not flow. The diffusion of bubbles is amazing. Recommended.

  • An actual improvement in ceramic disk CO2 dispersers
Size: S-13mm
The media could not be loaded. I can’t speak to whether or not customers may have received faulty product from earlier (or later?) versions or old stock, but I had excellent results right out of the box. (video – the Fzone diffuser is the one on the right) I’ve read a lot about slow-moving or discontinued items being promoted as “newer versions” in order to move old stock off the shelves, as well as companies compromising quality or materials to stay afloat in a distressed economy, which explains why I see so many disparaging reviews about newer iterations of the same product. The rating I gave this not an endorsement, but a simple account of my own first experience with it. I’ll probably buy another. UPDATE: Manufacturer responded to my inquiry about how to keep diffuser disk from getting algae clogged over time. They suggested couple of hours soak in citric acid solution. I substituted the citric acid for H2O2. Worked great. I'm guessing a soak in Flourish Excel might also work. I also read somewhere that bleach soak may dissolve the glue that seals the disk to the bulb. I previously used the Fluval mini-tire-shaped diffuser with good results, but they require more frequent unclog soakings, and bubbles grow larger as CO2 pressure drops, whereas bubbles remain consistently small passing through this Fzone disc, even as CO2 pressure begins to drop. I like these Fzone diffusers a lot for my D.I.Y. CO2 setups. I will be ordering more for my planted tanks. Also, they are made from a hard plastic, not glass. Not unbreakable, but less brittle than glass. ... show more

  • Watch out! It's smaller than it looks.
Size: L-24mm
The media could not be loaded. First I bought the smaller size and it was really small lol So I bought one size bigger (L?) and look how nice the bubbles come out! I feel like I'm watching a movie. Your plants get vivid if you have CO2 so this was definitely an essential item for my DIY CO2 kit. pros: Works great for your CO2 kit. cons: M size might be tinier than you think. ... show more
