CO2 Regulator/Bubble counter?

I have been trolling around on here for awhile now. I have a DIY CO2 sytem with a powerhead reactor on a 10gal. tank. (These are the plans I used)
http://www.qsl.net/w2wdx/aquaria/diyco2.html

I was wondering how to regulate the amount of CO2 in the system or exactlly how do you measure the level of CO2? Would a bubble counter help?

I am a newbie to this so go easy on me.
Thanks for any help.

You need a PH and KH test kit to measure the amount of CO2 in the tank.

If you want to know bubbles per second- do you have an air stone on the end of the air line? If yes pull it off and count how many bubbles come out

You need to test the water to be sure that you have the correct amount of CO2 disolved in the tank

If you have a low light intensity for that tank, you might be better off using Seachem Excel instead of CO2. You didn't tell us enough about the tank to know for sure.

Sorry about that. I have a 10 gallon with layer of Laterite substrate. The tank is about three and a half weeks into maturity. I have an amazon sword, java ferns, anubias nana, anubias broad leaf and a crypt. The plants are starters for now until I figure out what I'm doing. I use a AH 36W high intensity light kit and I have 4 tetras in there. My water parameters are:
PH-7.8
KH- 6.7
GH- 16.8
NO2- 0
NO3- 30ppm

I have some ferts on the way.
I guess my question is, how do you control CO2 injection?
Thanks

It isn't easy to control DIY CO2 like it is with pressurized CO2. One way which I have read about here is to put the CO2 bottle in a water bath, with a heater in the water, and regulate the water temperature to control the rate of CO2 generation.
