I have a small 1/4 acre pond in my yard. Built April of 09. Pond has been cloudy since its conception.I pumped 480 pounds of gypsum in slurry into it a few weeks ago. It helped some.now my visibility is maybe 12 inches. I even put 2 bales of pure alfalfa hay busted up into flakes trying to get some algae. I tried the quart jar of pond water and the vinegar, that cleaned it up quite nicely.Should I just dump 25 gallons of white vinegar into the pond? It would be cheaper than alum or gypsum. Do you guys think my next step should be alum? Or more gypsum?Or try the vinegar?
