What a surprise! I looked at the 10 ft across puddle in bottom of the new pond just a bit ago and it is crystal clear. Yesterday a couple hours after the 0.55 inch rain, it looked like creamed coffee.
Maybe I won't need alum? Maybe there is some natural alum in the clay? The 13 month old minnow pond about 60 feet away has never cleared more than maybe 8 inches visibility. Baffling!
