TJ, could you explain how the water column could be cleared without killing the excessive standing weight of algae that Ken referred? There is a distinction of course between a toxin and something that deprives an organism of nutrients or other necessities of life. Either way, the absence of bloom would be evidence that the algae died as a consequence of the treatment.
Could any other moderators comment on whether Alum is indicated when a large standing crop of algae is present in the pond? I could see this as a preventative measure but it does seem somewhat risky if a lot algae is standing.
