Review: Good first time diffuser - honestly this product for a first time co2 system is a good product. The bubble sizes are good and the design is nice. For the cost you are definitely getting the quality you get which is functional and good. I bought two, but broke 1 while removing the tubing from the diffuser. Overall satisfied with this product. Also you gotta marinate the diffuser in water for the bubbles to come out finer.
Review: U shaped part was broken - The U shaped part was broken before I ever got to use it. The rest works wonderfully.

## Features

- 【MIni Glass CO2 diffuser】Ideal for small tanks. 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. (No need to return the injured item)
