Reactor or inline diffuser

depends...there are advantages to each system.


Reactors can add head pressure to a filter and dissolution of CO2 can change based upon filter flow through changing as it collects detritus over time, so are best run on an independent loop.


Atomizers can leave a bubbly haze in the tank at higher bubble rates and can give false high readings on drop checkers. They won't restrict filter or pump flow.


Both will get the job done. Reactors tend to be better on large tanks whereas atomizers or inline diffusers do well on medium to small tanks. It really depends on your application and equipment setup.


I've used both with success. Inline Atomizers tend to be a little easier to setup and maintain in my opinion.
