Thanks all. I thought one of the benefits of aeration was reduced algae. But my buddy might have too much aeration, and that would cause algae.
I have zero history on this pond. I don’t know the fish population, or density. I did see a dozen or so geese on the bank, that’s probably the cause.
Obviously there’s a lot about ponds I’m still in the dark about.
Thanks again


12 yr old pond, 1 ac, 15' deep.
RES, YP, GS, FHM (no longer), HBG (decreasing), SMB, and HSB (only two have been seen in 5 yrs)
I think that's about all I should put in my little pond.
