We have a newly dug pond, approx 70' x 120', 16' at the deepest point, in heavy clay soil. It's about half full and really muddy. We spread 2 bales of hay around the permineter and within a week it was getting clearer, just like it is supposed to. Then we got a heavy rainstorm and now it's all muddy again. What is your experience with hay? Does the hay continue to help clear the water or is it a one shot thing. We haven't stocked any fish yet, but don't want to do chemical treatment.
