You only need to add enough drops of bromothymol blue (the pH reagent) so that the colour is easy to read. If you add too much, it will become too opaque to view.

As for the surface area, even with a small surface area, the colour of the indicator solution will change (assuming you have enough CO2); the only difference is that the reaction time will be slower.
