Suitable for pressurized CO2 supplying systems. High-quality glass material ensures transparency and durability. - 【Upgrade Widen U-Tube】Some customer complain that the U-tube is too narrow to hang on ther tank, so we made it wider. It is suitable for tank thickness less than 1 inch. The u-tube will avoid clogging due to bending of CO2 tubing. - 【Acrylic storage box】In order to avoid glass breakage during transportation to the greatest extent, we made acrylic storage box for each diffuser. - 【Fine bubbles】Premium ceramic piece produces fine and even bubbles. Ceramic pieces are non-removable and non-replaceable. - 【Working pressure】This diffuser requires at least 14PSI working pressure for optimal operation. Fits 4/6mm (3/16" Inner Diameter) CO2 tubing. - 【After sale service】If you encounter glass damage, please contact the seller for free replacement.

The rest works wonderfully. ### ⭐⭐⭐⭐⭐ Cheap co2 *by K***R on March 31, 2026* I modified this so I could use yeast instead and it works really well. For my 20 gal the yeast mixture lasts almost 2 months before I have to change it. I have a really hard time remembering to turn it off at night tho ## Frequently Bought Together - Clscea Aquarium Glass CO2 Diffuser Atomizer with U Tube Check Valve Suction Cup Premium Version - FZONE Aquatic CO2 Glass Drop Checker PH Momitor for Aquarium Plant Fish Tank Test CO2 Kit --- ## 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.tw/products/336202996-aquarium-glass-co2-diffuser-atomizer-with-u-tube-check-valve](https://www.desertcart.tw/products/336202996-aquarium-glass-co2-diffuser-atomizer-with-u-tube-check-valve) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-04-23*
