Yeah I realize that the barley straw takes 4-6 weeks to really begin working.

Our pond is about 5 years old. 100' in diameter and about 6-8 feet deep in the center. We had a fishkill two winters ago but the pond was naturally restocked later that spring. Our pond is in a low lying area just east of a small lake, due to heavy rains the lake overflowed the road and flooded our low lying area. There are quite a few small (2-4") bluegills & perch in the pond now. There is very little vegetation in the pond other than algae at this moment. As I said there is a drainage pipe from a nearby road that leads into teh pond along with runoff from our yard so controlling the amount of nutrients entering the pond is quite difficult.
