I can take a few pics next week. I tried to ID the emergent plant with the website Aquaplant but the closest match seemed to be duckweed. The plant in my pond has long stems with the little tiny leaves. I'm not sure it is a problem. Some plants are good for oxygen.
Would anyone advise planting water liily in the shallows to provide shade and cover? The small shallow pond looks like it would be an excellent candidate to plant them for aesthetics and controlling FA>
