[APD] High CO2 results in low NO3 uptake

[Michael Eckardt <mike at odg_com>]

Hi Daniel,

IMO, this is not scary in our realm of aquatic plants. This supports a 
number of assertions, especially:
- why algae blooms are triggered by NH4  and not high NO3 levels
- why CO2 fed tanks are generally algae free
- why some root feeding is good for plants (resurrect the Jobe sticks!)
- why a supplemental biofilter is useful as a NH4 sink.

I'm sure there are more. So it's not as bleak as it sounds - for our 
tanks. Different story  for agrigulture.
