The purpose of a CO2 reactor is hold the CO2 bubbles in downward current in a column of water so the bubbles stay in the reactor. So CO2 bubbles don't reach the tank and escape to the water surface.
Thus provided bubble free tank and hopefully more efficient use of CO2
You realy should ask them but i guess that''s true. I had my homebuild reactor on a Eheim pump with a separate intake and outflow.Does this mean that if I got one I would be able to use it with a seperate inlet pipe and a spray bar to disperse the CO2 straight into the tank
Like the sound of that. Had thought of adding a small pump myself to create a swirl effect, but finding time to find the right parts and the fitting them together in a leak proof way that can handle the pressures doesnt really happen ATMthat the new model with a pump attachment, is to create a swirl effect.
