PACKAGE INCLUDED: 1 x Inline CO2 Diffuser 2 x Hose clamps 1 x screwdriver Review: I been using co2 inline for a while now, the ceramic cylinder type one, i was a starting to loosing performance, I was due for maintenance.. So. While one is in service, I would have one in bleach solution for cleaning, so I tough why not purchase another one.. Based on desertcart recommandation and many positive review i had really high hope and excited to try this one.. Delivery came, started reading instructions, inspecting the diffuseur, I tried screwing co2 line into it for test fitting, screw it firmly and the tip broke.. Didn't even have the chance to try it out.. So just for that I would be giving it a 1 start rating for fast delivery... And minus 4 star for quality of product. Let's hope it's only a assembly or quality control problem and I was just badlucky, other user won't have water leak down the road 😉 Review: Works better than expected, no micro bubbles but just a fine mist out the lily pipe. Highly recommend 👍 ## Features - 【Inline Design 】 100% Open Flow Design. There is no limit to the filter flow.

Highly recommend 👍 ### ⭐⭐⭐⭐⭐ Review *by F***V on 4 September 2023* For me, these in line diffusers, which I have both sizes of an multiples of, are the perfect way to diffuse CO2. Best dispersion rate in the tank and zero noise from a fizzing CO2 stone. Perfect. ## Frequently Bought Together - Clscea External Inline CO2 Diffuser Atomizer Aluminum Alloy for Planted Aquarium 16 mm - FZONE Aquarium Co2 Regulator DC Solenoid with Bubble Counter and Check Valve Plant Grow DIY CO2 System CGA320 Side Open Cylinder - FZONE 16 feet Aquarium Co2 Proof Tubing 3/16'' ID Black Food Grade Air Line Tubing --- ## 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.in/products/511889881-external-inline-co2-diffuser-atomizer-aluminum-alloy-for-planted-aquarium](https://www.desertcart.in/products/511889881-external-inline-co2-diffuser-atomizer-aluminum-alloy-for-planted-aquarium) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-04-26*
