I have a small .05 acre pond that I am using to grow out some CNBG. I applied lime about 1 month ago and liquid pond fertilizer a few days ago trying to trigger plankton bloom. The water has been a light brownish color intil the last 2 days. Its now closer to a coffee color. I dipped some water up in my hand and it was crawling with nearly microscopic creatures which I am assuming are daphnia. I know they are a desirable part of the food chain and the fish seem fine. Is it normal to have this happen. Pics give an idea of water color.
