What is the purpose of a Cerges CO2 reactor?

I have seen drawings and diagrams, on how this goes together and to be honest I found it totally by accident. It looks a fairly simple thing to make (they all do until you start) but what exactly does it do and why?

How does this benefit my plants? I understand the basic concept of mixing the water with the CO2, but how is this better than any other form of introduction of C02?

Please do not misunderstand me here, I am NOT trying to be argumentative in any way shape or form. Just trying to get things straight in my head.

Thanks in advance

The advantage of rex grigg and cerges type reactors is they can reach near 100% dissolution of co2. In tank diffusers will never reach anything near that.

I just built one. When I hooked it up I didn't change the flow rate and almost killed my fish.

That looks good. Kudos on finding the right connector parts/adapters! Agitate the surface of your water if you are not already doing so. It ought to let you push your CO2 higher while keeping the fish satisfied.

You can absolutely make one your self. It disolves the co2 more efficiently, in-line without any escaping into the air. Also adds surface area for bb. There's media in the tube
