Hi, I have a new (2 years old) pond about 100x100 10ft deep in South Dakota. I use a small pond pump to circulate water in the winter and it keeps a small area open (10x10 area) I have hair algae starting to form floats to top and want to control it with algae eating fish?? I do have some large mouth bass in pond. not much vegetation yet.
Welcome to the forum! That is a big pond! And, you need it in such a cold climate. I know people want some magic answer to dealing with algae, especially hair algae but the truth is that most animals don't like to eat hair algae. There is no fish you could add that would make much of a difference. I suggest aeration which you are doing, good bacteria, barley straw, and lots of live pond plants. There is too much to go over but if you have a specific question, let me know.
