What is the speed with which plants take up all these nitrogen compounds? 
I imagined that nitrates and ammonia in solution would be actively 
transported into plant tissues upon contact. Java moss should act as a 
nitrogen vacuum cleaner, no?

Per the carrying capacity of water, what is the relationship between O2 and 
CO2?  Is it one of competitive exclusion?

Given what the plant people do to their tanks with CO2 injection,  a 
competitve exclusion scenario would kill fish pretty quickly I would think; 
Especially given the higher solubility constant for CO2.
