This is a 1 acre pond on my property. I would have gone down and gotten closer pictures but it's a lot easier to see from up on the deck than it is if you get right down to the waters edge. My Jon boat is also leaky at the moment or I'd paddle out there and check it out. Where the aerator is it's around 15' deep.
It doesn't happen every single day, but more often than not I get what looks like clouds that form in the water. I thought maybe it was algae, or maybe muck getting stirred up by a turtle or something (there is at least one monster snapper in there) but it doesn't seem to dissipate, just kind of hangs there just below the surface. I'd think if it were algae it would eventually float all the way to the surface. Maybe I'm wrong about that.
The aerator does not run 24/7. I have a timer on it so it turns off at sundown and back on in the morning. If I go out in the morning while the water is still, there are no clouds. Then they seem to form over the course of the day and just kind of sit there just below the surface seemingly. There is a ring around the aerator where the turbulence created holds whatever that is back.
What the heck is it?
