Thanks VaughnH, is this for DiY CO2 applications? I have my only co2 tube in the inline reactor? The powerhead is a small maxijet, and I think it has a spot to put an airline tube into it already? It is submersible too, so is the benefit of a mist application and doing it this way, the ability to place the powerhead down deeper in the tank? I really dont understand this at all. I dont see bubbles coming out of my spray bar, so I "assume" its being dissolved well, but with it being dispersed at the top of the tank out of the spray bar, I dont know how well it reaches the bottom of the tank?

Thanks very much, and sorry for a bunch of questions that have prolly already been brought up, and trust me I prolly read it on here, but just dont understand it or its benefits

If what I have is good, then I will just let it go....just curious if I could make any "tweaks"?

Thanks again
