After last nights video on aeration, I have a question for the folks who have ponds in the upper mid-west and North. i am in Michigan. Spring is about to hit us ( we all hope) and I have my aeration in the 3-4 foot area for winter to keep the ice from my dock and to keep open a fairly good size hole. I have two aerators in deeper water and in the spring I usually just shut the shallow off and the deeper on. Question ....How do all of you do this? i have not had a problem with fish kill in doing it this way, but, the pond is now three years old and so are the fish. I am just curious as to what others so in my region of the world...thanks for any comments!!
