I was wondering what kind of reactor you are using for your tank or one that is the most efficient to dissolve co2. I have a 20g tank with a glass diffuser. I was thinking of changing it to a reactor. Do they have any cheap one? for a 20g. Also how would you set it a co2 reactor anyways. I read that somewhere some people connect there co2 to their filter? How does that work.

I got a co2 tank and xp2 filter.
