- Splits CO2 between multiple aquariums
- Individually adjustable CO2 output
- Easy to install
Easily run CO2 from one cylinder to multiple different aquariums using expansion manifold blocks. These handy manifolds screw into the existing CO2 regulator system and to each other for the ability to link up to 5 expansion manifold blocks together (for a total of 6 aquariums connected to one CO2 cylinder). Simply add one block for each planted aquarium you'd like to inject CO2.
