I agree!! Bacteria have exponential growth that is determined by the amount 
nutrients available to continue growth and reproduction. A population will 
level off and maintain a balance proportional to nutrient level. If foods 
increases so will the population.  What I find interesting is that we all 
agree that higher plants will eventually out-compete algae for nutrients, 
provided there isn't an excess of nutrients. Does this not work for plants 
vs. microbes? 
I am not saying that plants can wipe out a bacterial colony in our aquaria, 
but isn't it reasonable to suspect that the plants are more efficient at 
competition for food?
