Craig,
I am just curious as to what causes blue green algae? I know that relies on photosynthesis but apparently there must be some sort of nutrient requirement for the bloom to occur? I had thought that it only affected mostly stagnant waters but it seems that it can affect even large bodies of water with considerable agitation.
Can you elaborate at all on what conditions are favorable for Cyanobacteria to help me understand what causes this and is there anything that can be done to prevent this?
