Grow aquatic plants faster by injecting pressurized carbon dioxide in your planted aquarium. Using the Aquarium Co-Op CO2 regulator will ensure a steady and reliable release of CO2 gas as it features a dual stage design. The two easy-to-read gauges show both tank volume and working pressure. Included is a bubble counter for easy adjustments of CO2 levels as well as a solenoid valve which can be plugged into a timer for precise timing of CO2 release.

Multiple manifold blocks can be added to this regulator to expand your CO2 system to multiple aquariums at once. Each manifold block features its own bubble counter for precise adjustment of gas to each aquarium individually.
