If you need to inject CO2 into more than one diffuser or aquarium, the CO2Art Manifold Block comes with everything you need: 

• Included Bubble counter with high precision needle valve

• The bubble counter comes up with a built-in check valve permitting the water to flow in one direction only protecting the regulator from damage

• Tools to install the block onto your already existing manifold

• With this effortless installation, your additional diffuser will be up and running in no time. 

The Manifold Blocks are fully tested in terms of resilience and leaks to provide the user with total reliability and quality. You can run 5+ Manifold Blocks at the same time, adjusting CO2 individually with the high precision needle valve. 

If you want to run multiple diffusers with one CO2 regulator and cylinder, the CO2Art Manifold Block is your MUST HAVE! This clever device allows you to inject CO2 into more than one diffuser or aquarium independently by extending the already existing Manifold Block of Pro Elite CO2 Regulator. Before ordering, please check if you have the Hex-type screw block, if you have the old Philips-type screw type please leave a comment during checkout or contact our support team.
