After talking with local proffesionals and State Fish Biologist I applied 15 lbs of copper sulfate to this 4.5 acre pond. The algae has drastically cleared up with some remaining on the bottom.
Tonight I found my lone 4-5' grass carp floating in the shallow area in the process of dying. Every now and then he flips his tail but it is only a matter of time. I am surprised in that I figured with the pond being 4.5 acres and 24-30' deep that the carp would be able to survive. I only applied the chemical from the bank and it was a very sunny day.
The remaining fish are very active around the shore and they are all different sizes. They do not look stressed at all. The carp was pretty old so maybe it is a combination of things. The temp have reached the mid to high 80 range the last 2 days. I applied the majority of the chemical Sat morning.
