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!

I purchased this diffuser after purchasing an Fzone regulator and being very pleased. This diffuser replaced a Fluval that was a little disappointing. I was impressed with the amount of bubbles and how fine they are. I placed it underneath my filter output so it blows the bubbles across the tank and I'm very happy with it. I'll purchase the small size for a different tank now because the CO2 comes out so fine. Very happy with this purchase.

Out with the old, IN WITH THE NEW! Neo diffusers are of the new era! Incredible output of microscopic bubbles, which means the diffusion of CO2 into the water column occurs at a much higher rate compared to glass with ceramic disks. Incredibly happy with this upgrade!
