There is a good article in Pond Boss Magazine this month about the difference in planktonic and bluegreen Algae (actually a bacteria) and their effects on the pond community.
Might be worth your time to get your hands on a copy.
I also have problems with what I am pretty sure is bluegreen algae in the heat of the summer. I wish I understood all I knew about it and I don't know much.
There is definitely a difference and the bluegreen algae is undesirable for a number of reasons.
