Aireation-- I'd love to but I cannot get power to the pond and right now the budget won't allow it.
I did have the DO tested yesterday at 7:00 a.m. at the 8 foot level off the end of one of the docks. The reading fluctuated between 7.20 and 7.35 even with a large amount of decaying vegatation and being at the end of summer with the water still pretty warm and tested early in the morning. As I understand it, that is a pretty good reading but that the DO will vary in different parts of the pond and at different times of the day. My questions is--is it necessary to test the DO during the winter months, even cutting a hole in the ice to do so? Are the necessary numbers the same during the colder weather or is less DO required?
