I suggest you look at an ionic liquid flocculant, once your ice thaws. I used two gallons ($62.50 each) for my one tenth acre seven foot pond. Suspended sediments included some clay and limestone dust. The first gallon took it to about two feet clear within a day. So I spread another gallon. Dumping diluted along edges and tossing out diluted from a bucket. The second gallon got me another foot of clarity. I found my blue dye was blue, not green. The fish on the bottom are stirring the water and the sediments, but they still settle out. I have bentonite but I'm out of the floc or I would try an experiment to floc and sink bentonite. I will be getting more floc come spring...love the stuff for my small pond.
