Some turbidity can be a benefit as it reduces light penetration which reduces amount of new plant growth. The clearer the water the more and deeper ALL plants will grow. Then most resort to a heavy dose of blue dye which then selects for algae that are tolerant of blue dye.
Bacteria are a big waste of money, as you now know, if turbidity is due to suspended silt-clay or phytoplankton that could be suspended in the water column for numerous reasons - causes.
I would research the environmental fate of Karmex. It or some other by-product that could persist in the sediments based on what chemical 'soup' was in the pond during application. You do not know how much has been applied in the past which could have been a lot. I would not let my kids swim in a Karmex pond. Mucous membranes are very permeable to chemical exposure.
