I'm finally getting some good grass sprouting on 3/4 of the banks. Assuming i can keep it alive through the rest of this summer and stop the mass inflow of mud into the pond i would like to try and clear it up some more before putting in any more fish this fall. Where can I buy large amounts of gypsum? I can buy 40# bags at lowes, but if i remember correctly i'll never several hundred pounds for my .4 acre pond.
