CO2 Resistant tubing is the best way to transport and deliver CO2 to the planted aquarium. We do not sell silicone tubing which is highly permeable to CO2. With our CO2 resistant tubing, CO2 will not escape and every last drop of CO2 will be put to efficient use.
The check valve permits flow in one direction only, to prevent the flow of water into your CO2 regulator. Protect your investment with an inline aquarium check valve. It is essential to every CO2 system setup.
