The Carbon Dioxide Refiner Hard Pipe is a pipe with a U shape that removes impurities from carbon dioxide gas. It is made of acrylic and has high intensity. The gas flows through the pipe, and the impurities are caught in the U-shaped section. The purified gas is then discharged from the pipe and can be used for a variety of purposes.
Features:
Type: Fish
Type: U-shape tube
Material: Acrylic
More About The Product
Performance: Our aquarium cleaning tool uses no electricity, has a large output, and extended service life while operating quietly and efficiently.
Easy Usage: This little purifier may be linked to the included air stone, which produces bubbles, to provide added appeal and air to your beautiful fish and aquarium.

Frequently Asked Questions
This CO2 refiner has a U-shaped design that routes carbon dioxide gas through a curved path, allowing impurities and undissolved bubbles to settle out before the purified CO2 is released into the aquarium water. This improves CO2 diffusion efficiency in planted tank setups.
The pipe is made from acrylic, which is chosen for its high clarity — allowing you to visually monitor CO2 bubble flow and check for blockages without removing the pipe. Acrylic is also chemically inert and will not react with CO2 or aquarium water.
The pipe comes in five lengths: 15cm, 20cm, 25cm, 30cm, and 35cm. Longer pipes provide more refining distance for the CO2 flow and may suit larger tanks or setups where the CO2 diffuser is positioned further from the tank wall. Match the length to your tank depth and diffuser placement.
By routing CO2 through the U-shaped pipe, undissolved bubbles are captured in the curved section rather than escaping directly to the water surface. This increases the contact time between CO2 and water, improving dissolution rates and making your CO2 injection more efficient and cost-effective.
The acrylic U-pipe is designed to fit between a CO2 regulator or diffuser and the tank inlet. It connects via standard CO2-compatible silicone tubing. Check the pipe's end diameter against your existing CO2 tubing inner diameter to ensure a gas-tight connection before purchasing.
Rinse the pipe with clean water periodically to remove algae or mineral deposits from the interior. Acrylic is scratch-sensitive, so avoid abrasive brushes — use a soft pipe brush or soak in a diluted vinegar solution to loosen deposits. Inspect the tube ends for cracking if the pipe is removed and reinstalled frequently.
