If we attempt to find ways to only remove the algae we will not be able to stop the problem. I think we need to figure out the cause of the algal blooms first, then we will be able to figure out how to stop it from reoccurring once we remove what already sits. Then once we understand the cause we may be able to artificially create the algae in safe conditions to be used for its positive resources.
