Also, do you think that adding 100 lbs./acre ft. would be what is needed since I recently added 60 lbs./acre ft. or should I add another 125-150 lbs./ acre ft.? The source of the high ph is a mystery to me. There is no cementious material in or at the edges of the pond that could leach in. The main watershed is a farm field that has a tile running into the pond. Do you think that could be a source of high ph? There is a new generation of bluegills and LMB and we are even catching some small channel cat.
