CO2 Tubing

Marine Depot has quality CO2 tubing, CO2 resistant tubing that delivers carbon dioxide from the CO2 tank into the aquarium.

CO2 proof tubing prevents carbon dioxide from escaping through the tubing. Regular airline tubing can cause a 20% loss of CO2 . CO2 tubing has a 4mm inner diameter, 6mm outer diameter, and can fit on standard airline fittings. We recommend that you attach a CO2 check valve to the CO2 tubing. The check valve ensures that water does not flow back into the CO2 regulator and damage the components. CO2 airline tubing can degrade over time, so it should be replaced periodically.
