<<With a CO2 controller, the CO2 in your tank is always the same everywhere. There are no hot spots, dead spots, changes with plant and fish activity…no changes period. Now the average CO2 level at one location is the exact CO2 level for the whole tank>>

This is not an opinion this is a scientific fact!

If you go here and open CO2 paper part 2 and go to table 3:

You will see that there is only a statistically insignificant variation in CO2 levels in a typical CO2 controlled tank.

I think are referring to a (CO2 in = CO2 out) system. In these uncontrolled systems the range in CO2 levels can be almost 100 fold.
