RStringer, did ANY sediment settle on the bottoms of the jars when tested? If there is no settled out particles after even 3 days, the turbidity in unlikely to be mechanical (wind/wave action, fish). IIRC you said somewhere your pond is 1/8th acre? At 1/8 acre, I suggest going ahead and treating your pond "heavy" with 200 pounds Aluminum Sulfate and 100 pounds of Hydrated Lime (Calcium Hydroxide). Cost is very minimal for staggeringly positive results.
