While you are at this, have you considered the toxic effects of algae: blue green algae, and the famous red algae that give us the "Red Tide" that kills a lot of fish.  There are several types of algae that are toxic in different ways: cattle have been killed from drinking from tanks with excessive algae.  Know the species.  Things have changed (a lot) since I did my graduate work in this field and i became involved with Industrial Water.  For 40 years I have been removing PO4 and nitrate/nitrites from water with bacterial to limit the growth of alage - they use the same food source.  An interesting fact in growing the bacteria we use and the algae we don't want is that the pH is a limiting factor for the many algae below about 8.2 and the limiting factor for the bacteria we want above 8.2: the point where P alkalinity starts, and the point that most affects the carbonates and bicarbonates.   On site bioreatctor have been in use for over 40 years with some very good results for growing large amonts of organisms to treat specific application.  The idea is to install growth tanks, specific starter organisms, feed them and watch them grow and reproduct; this lowers the cost of application.  The downside is that because these organisms reporduce rapidly (mine double in population every 15 minutes). they, in the beginning eat everything given to them and do well.  That means that the population is doubled 2,880 times in one month.  Hello evolution: the population has changed and at least 1/2 of the population has gotten lazy and let's Joe over there to the work - why should we work and make more enzymes when Joe can do it.   Time to dump the tanks, clean them out and start fresh and purchase pure strains of the organism we want.  Good Luck.  But I believe that you will find that most of the objectives of this project will find that the results will be species specific.
