This is my first time using c02, and this diffuser works great for my application; I have a 32 gal tank, with snails and fish. Instructions say to soak for three hours but it was at least 24 hours before I could get back to it after hanging it in the tank. After completing setup I turned it on and....voila!! Tiny bubbles! The instructions stated initially bubbles would be big but would settle down after a couple of days to tiny bubbles. I think the extra soak time probably prevented that situation. The only problem I have with this diffuser is the shape. I liked the look of the long neck with hook at the top but it doesn’t fit over the edge of my tank very well. My tank is Bio Cube and we’ve removed the hood and placed a Finnex LED light on the open top. The rim where the hood closed is pretty thick, and the hook of the diffuser isn’t wide enough to fit easily. It doesn’t bend easily and would possibly break if forced. I’ll use it until I get a different one, and will keep it for rimless tank setup later on. It does work well! ### ⭐⭐⭐⭐⭐ has worked well for a couple years now *by A***R on February 15, 2023* there are many choices but for my CO2 setup in my planted aquarium, I prefer having a stainless steel diffusor and this one works great, does the job and allows for easy maintenance. Every 8 weeks to clean the diffusor disc, I let the disc sit it in small tray with 50/50 mix of Chlorox/water for a few hours, scrub and rinse off well, reassemble and the CO2 system is good to go for another 8 weeks again. I have had this unit working over 2 years now with no issues other than there may be some slight imperfections in the quality of the stainless but overall it works excellent and is easy to maintain. ### ⭐⭐⭐⭐ Much better than the glass diffusers and aesthetically nice also. *by A***R on March 1, 2018* Compared to all of the other diffusers I used, this is my favorite so far. The quality is great, really sturdy/solid and beautifully designed. I did not have to worry about putting on the CO2 tubing (the black rigid kind) and breaking the diffuser like some of the ones that are made out of glass. The bubbles are fine and evenly dispersed (some of my other diffusers have various size bubbles coming out of the ceramic membrane). No cheap plastic suction cup to hold the diffuser in place either. This works well with my rimless tank, but on my larger braced tank, I had to cut a small piece from the aquarium bracing for the diffuser. This is because the curve at the top of the diffuser can only support 1/2 and my aquarium + brace is 3/4 inch. Cleaning the diffuser is easy, just unscrew the top and clean the ceramic membrane without worrying about breaking anything. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/117261871-co2-diffuser-for-aquarium-excellent-co2-solubility-ensuring-vigorous-plants](https://www.desertcart.tn/products/117261871-co2-diffuser-for-aquarium-excellent-co2-solubility-ensuring-vigorous-plants) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-06*
