CO2 Reactor — Internal

The internal CO2 reactor offers the dissolution efficiency benefits of reactor-style CO2 injection in a self-contained unit that requires no canister filter for installation. It mounts inside the aquarium and connects to any power head or internal filter output, using the flow of water through its mixing chamber to dissolve CO2 injected from the CO2 line. The turbulence generated by the impeller or static mixer inside the reactor ensures CO2 bubbles have extended contact time with the water before being returned to the aquarium. This makes it far more efficient than a simple in-tank diffuser and suitable for aquariums where a canister filter is not available. The compact body is designed to be as unobtrusive as possible inside the tank.
