Why the Fish Died

Explanation of how excessive fertilizer will kill fish in a pond.

So I just built a 1/4 acre pond one year ago. It is filled with a well and is 16 feet deep. I stocked two large female bass along with 600 small bluegill. Everything was going great for a couple months and then I added blue pond die. The next day the fish were at the top gasping for air. I lost both bass and 10-12 bluegill. A month goes by and I add two more female bass. They do fine for a couple months and I add more pond die. Once again I loose both bass and a few bluegill. What is happening when I die the pond? Everything I read says pond die is Great!
