Curious how much a 1/2 HP circulator adds to ones electric bill each month. Never had any dock damage without one in the last 51 years. New folks around us have started using circulators, some of them without timers apparently. Lots of birds living around the edge of the open water. One place where snowmobiles and ice fisherman used to get on and off the ice has been open water now for the last 8 years due to circulators.. seems like a monkey see monkey do thing for many of them.
