We are located in East Central, Indiana, have a one acre pond, 20' deep. We have a 5 ton Carrier geothermal unit with closed pond loops. We, also, have a Koender's Windmill with an air stone. What affects would this aeration have on the pond loops? Does aeration have harmful affects on geo in a pond? (you probably already know from other thread that my pond loops have floated to the surface stuck to the ice)....Could aeration really have made these pond loops float? Thanks.
