This is for one separate CO2 manifold block and does not include the UNS Pro Dual Stage CO2 Regulator. Connecting multiple manifold blocks to the Ultum Nature Systems Pro Dual Stage Regulator allows for CO2 distribution into multiple planted aquariums using one cylinder. Add one extra manifold block for every planted aquarium you want!
Each manifold block consists of a detachable bubble counter, check valve, and precise needle valve. Increase the number of manifold blocks used to create hassle-free and simple planted aquarium CO2 injection systems.
