Hi,
Like a lot of people, I have my CO2 come on about an hour before the lights come on.
I am not sure though whether after 1 hour the CO2 has reached sufficient saturation.
I gave up using drop checkers because of the way they can be misunderstood, slow response time etc.
Could I draw any conclusions as to how 'fast' the CO2 is kicking in based on pH measurements alone? For example, if I measure the pH as the CO2 comes on, and then 1 hour later when the lights come on, measure it again, could I draw any conclusions based on the colour shift? i.e. I don't really care what the actual value is, rather, the change alone?
If CO2 is being injected effeciently, what would this change typically be? I have heard it should be 1 unit of pH, so, I guess if it measured something around 7 at CO2 on and then about 6 at lights on 1 hour later, that would be pretty good?
Scott.
P.S. If CO2 can measure differently at different locations in the tank using a probe, does this suggest that pH various throughout the tank too?
