drop checkers with mist vs reactor

Hello all -

In my quest to understand the CO2 world this question occurred to me:

If a drop checker requires the CO2 to be dissolved in the water to 'register' the right color, what does this mean if you are misting CO2 instead of dissolving it completely?

For example, if I run x bubbles/second of CO2 through a reactor and the DC turns green, should it turn green if I ran that same amount through a mister? I'm hearing that the undissolved CO2 in the mist is still readily available to the plants, so perhaps it doesn't matter, but are drop checkers less useful when misting?

thanks!

The mist still "dissolves" in the water. Use the drop checker in combination with watching fish and plants. Be careful and go SLOW. Fish will take a bit to adjust and taking a few days is much safer than going fast.
The CO2 from a mister still dissolves in the water, but generally not as efficiently as CO2 in a reactor. So, if you switched from a reactor to a mister you would probably have to increase your bubble rate to get the same dissolved CO2.

But the idea with mist isn't dissolved CO2. It's that CO2 is more easily absorbed by the plant from the tiny bubbles ( Don Ho anyone? ) sticking to the leaves than from the plant having to absorb the CO2 that's dissolved in the water.
And makes your tank look like a bottle of soda. I'd rather only see the pearling bubbles not millions of little tiny bubbles...
