I never knew these things were assumptions either. I have a huge text on 
all the nutrients macro and trace in relation to aquatic plants what 
exactly they do and what symptoms of their deficiencies are including  
how the symptoms from slow growing plants to fast growing plants can 
help show whether excess of one is out competing another in the 
instances where it's relevant. I just assumed I guess that it was correct.
