Thanks for the info

I have a fluvall fx4 and setting up a new 125 gallon planted tank and was recommended a co2 reactor instead of a diffuser for it. I was sold one that the ports are way smaller than the fluval hoses. Does anyone know of a reactor that fits the fluval hoses which are about 1” and the reactor is about 0.5”? Or can I reduce the line down to that size without causing problems with flow or pressure in the system? Any help will be greatly appreciated.
