CO2 & PH relationship
What does a change in PH say about CO2 levels?
My tank PH is approximately 7.6-7.7 prior to my CO2 going on. With in a couple of hours after CO2 starts up PH readings are 6.6-6.8 give or take. Is there some way to calculate CO2 levels (even approximate values) using these values? I do not have a drop checker only a Milwaukee PH meter and would like to now the best way to use it in conjuction with my CO2 system.
Can any one help?
