Thank you for the responses. The initial cause I believe was due to it being a brand new pond with soil runoff until it became filled. Once it was filled I still had runoff from soil erosion until I was able to get grass growing to secure the soil. It’s been about 6 months since that point and the water hasn’t cleared.

The Alum test definitely showed better results than my test using gypsum with my water PH level floating around 8 I believe I’d be a good candidate to use aluminum sulfate.

My concern after reading so many posts and videos regarding the jar test is that nobody had mentioned the suspended sediment floating before. I feel better knowing other people have had that issue. I will give the jars another 24hrs to see if things start to settle.
