Co2 And Microbubbles In A Large Tank

I have a large tank that I will be setting up as a high tech tank It's a 250 gallon with overflows. I also will be using a 40 gallon sump. What is the most efficient way to add CO2 to a large tank? It sounds like Mazzei injectors are very good at producing large amounts of CO2 but result in a cloudy mist in the main tank. Is there any way to minimize this? I was thinking of using a Mazzei 384 on a seperate circuit going into the sump first, it has a bubble trap. Would this work or would they just take out the CO2 I am trying to keep in the solution.

Are there reactors that can produce the required CO2 for a large tank without all the microbubbles in the display tank?

I would appreciate if anyone could tell me what would be the best way to go about this.
