10 acre pond in Central CA. Maximum depth is 8’. Pond has bluegill and bass. It is deep water well fed. No live stock. No other source of water. Have fish feeders on the pond. Visibility varies between 1’ -3’. Water temperature is 85. We have aeration with 4 large air diffusers running 24/7.

Good fishery. These weeds just got worse this year. We built the pond 7 years ago.

Help! What is this? How and when do we treat to get rid of it ASAP? Will it come back?
