You don't need any in the water. A CO2 injector and tank is the best way. It is hard to say just how much to add to a room without expensive meters to tell you how much is getting to the plants. Plants need about 1500 ppm in the room.
I pump 1 CFH - Cubic feet per hour of CO2 gas for 15 minutes ever hour. It also depends on the size of your grow room.
Here is the formula for figuring out how much your room needs.

Multiply: length x width x height of your room to calculate the volume in cubic feet.
You want to raise the CO2 level in a room to the optimum level of 1500 ppm. Generally, the CO2 level in a room is 300 ppm so you need to raise your room level by 1200 ppm to reach the optimum.
1200 ppm = .0012 Note: Multiply your room volume (from step 1) x .0012 to figure out how much CO2 to add to your growing area.
Example:
10' long x 10' wide x 8' high = 800 cu.ft.
800 cu.ft. x .0012 = .96 cu.ft.
(You can round this off to 1 cu.ft.)
This is the amount of CO2 you need to add to a 10' x 10' x 8' room to raise the CO2 level to 1500 ppm.
