saying goodbye to the "hail mary" of gas exchange
So now I'm on the eve of introducing pressurized co2 to my tank via inline reactor.
I've read that co2 easily degasses. Up until now, I've had the filter output 1/2 out of the water, to ensure o2 exchange. But the more threads I read, the more I think I'm gonna wanna cut that out.
My main concern is ensuring sufficint o2 exchange for the fishies. Also, I'd like to create a situation at the surface to maintain somewhat stable rate of co2 degassing, thereby a stable level of dissolved co2 in the water.
How exactly does everybody have their cannister output set? Slightly raised to where it breaks the water surface, or submerged but causing waves? Can I depend on a heavily planted tank and minimal surface movement creating enough o2 for the livestock?
