Thanks, I guess having the water checked is the next step. There is a place right in Raleigh according to the web search that I just did. That works. I will take it there next week and report back.
I couldn't find any place to test the pond bottom but I will ask the lab when I drop off the water. It is at NC State so I am guessing it is part of the big agricultural school.
Are nutrient rich ponds bad, good or just different? I am sensing from the comments that it is fine. Still, it seems very green to me.
