My Problems with my old pond have been solved with a rebuild:
i lifted all of the cement that was oosing lime into the pond and killing the fish, lastnight the ph was 7, its stayed at 7 all day long until an hour ago when it really started coming down hard (rain), it used to be when this happened the ph went straight to the top of the scale, I just went out and checked the ph, if anything it has fallen to just below 7 because of the acidity of the rain water, looks like my issues are gone
below are some pics of the pond in development and the final product
