It doesn't matter how long it takes, it's going to be the same for both

A top is not needed. You just capture the bubbles underwater.

The atmosphere is not going to have any effect underwater.

No port needed. Just use an inverted test tube underwater.

I'm not measuring what is in the captured gas at this point. I'm 
measuring how much gas makes it to the top to be captured. If CO2 
dissolves more slowly at 30 mg/L, then more gas will make it to the top.
